Laura Prepon: Age, Net Worth, Relationship History, and Career

Anyone who spent the late ’90s watching Donna Pinciotti roll her eyes at Eric Forman feels a jolt of recognition at Laura Prepon’s name. Now 45, she has moved from sitcom sweetheart to director, cookbook author, and — as USA Today has reported — one half of a marriage that stalled in September 2024.

Age: 45 years (as of 2025) ·
Birthday: March 7, 1980 ·
Net worth: $9 million (estimated) ·
Notable role: Donna Pinciotti on That ’70s Show ·
Spouse: Ben Foster (married 2018, separated 2024)

Seven facts anchor the bio; the pattern is how ordinary the core record looks — birth, roles, marriage, separation — even while the headlines around it got loud.

Who did Laura Prepon play on That ’70s Show?

Prepon became widely known for playing Donna Pinciotti on Fox’s That ’70s Show, the sitcom that ran from 1998 to 2006. She was a teenager when the pilot aired, and the role stayed with her for the show’s entire run.

Her role as Donna Pinciotti

• Donna was the sharp-witted neighbor whose on-and-off romance with Topher Grace’s Eric Forman anchored the series (Wikipedia biography)
• The series ran on Fox from 1998 to 2006 (Us Weekly profile)

Wikipedia’s biography describes the role as the one that made Prepon a household name. The character was written as Eric’s equal — confident, direct, and not especially interested in being the butt of the joke.

That positioning mattered. Donna wasn’t just a love interest; she was the friend who could ground the show’s ridiculousness, and the role has aged well in reruns and streaming.

Impact on her career

• Made her film debut in Southlander in 2001 (Apple TV credits page)
• Starred in ABC’s October Road from 2007 to 2008 (Apple TV credits page)
• Led NBC’s Are You There, Chelsea? in 2012 (Apple TV credits page)

The pattern in those choices is restlessness: a film debut, a network drama, a multicam comedy, then the sharp turn into prestige TV. That ’70s Show gave Prepon a durable base, but it never became the ceiling on her career.

The implication: Donna Pinciotti built Prepon’s public identity, but the roles she took afterward kept her from being frozen into it. When Orange Is the New Black came along, she was ready for a part that asked for something darker.

How old is Laura Prepon now?

The short answer: 45, as of 2025. The longer answer starts with a March 1980 birth date and a small New Jersey town.

Birth date and age

• Born Laura Helene Prepon on March 7, 1980 (Wikipedia biography)
• Birthplace: Watchung, New Jersey (Wikipedia biography)
• Age in 2025: 45, calculated from the March 7, 1980, birth date

Per Wikipedia’s biography, she was born in Watchung, New Jersey. She turned 18 in March 1998 — a few months before That ’70s Show premiered on Fox.

That timing matters. She was legally an adult by the time the show hit the air, which meant she entered the public eye at exactly the moment she could manage her own career.

Early life

• Documented childhood details are sparse in the cited reporting
• What’s solid: she was in front of a major network camera before turning 19

This is where a fact-checked profile has to stay honest. The cited sources confirm the birth record and the 1998 casting, but they don’t support the kind of childhood anecdotes that fill other celebrity profiles.

What the timeline does show is momentum: born in 1980, on a network sitcom by 1998, and in film by 2001. The pattern is an unusually linear start — one borough, one breakout role, one fast turn toward film.

What is Laura Prepon’s relationship history?

The headline version: a long friendship with actor Ben Foster became a romance in the mid-2010s, a wedding in 2018, two children, and a divorce filing in 2024. The sourcing on each step varies, and the legal record still contains a date discrepancy worth flagging.

Relationship with Ben Foster

• Became romantically involved around 2015, after a longstanding friendship (USA Today report)
• Got engaged in 2016 (Us Weekly profile)
• Married in 2018 (USA Today report)

USA Today’s coverage traces the couple’s origin to a friendship that predated the romance. Us Weekly’s profile places the engagement in 2016, and USA Today records the wedding as 2018.

The couple kept most of the relationship out of the press, which makes the public record thin at the start and heavy at the end.

Marriage to Ben Foster

• Daughter born in August 2017 (Us Weekly profile)
• Son born in 2020; not identified by name in public reporting (Wikipedia biography; Us Weekly divorce report)
• Court filing lists September 9, 2024, as the separation date (USA Today report)
• Foster filed for divorce in 2024, citing irreconcilable differences (Us Weekly profile)

The marriage’s arc is well documented even though the couple kept the relationship itself private. Foster filed for divorce in 2024, and USA Today reports that his court filing designates September 9, 2024, as the official date of separation.

One flag: the filing month isn’t consistent across outlets. USA Today describes the case around a September 9, 2024, separation date, while other entertainment reporting describes a November 2024 filing. For readers tracking the timeline, that gap is unresolved in the public record.

Co-star relationships with Mila Kunis and Topher Grace

• Stayed close to Mila Kunis, who played Jackie Burkhart, after That ’70s Show ended (Wikipedia biography)
• The on-and-off screen romance with Topher Grace’s Eric Forman was the show’s central relationship

Prepon and Kunis remained close after the series ended — a friendship that has outlasted the show itself. With Grace, the chemistry was primarily on screen, but it’s the on-screen pairing audiences still remember.

Those bonds matter for the reunion economy. When That ’90s Show brought original cast members back, the goodwill between the actors was as much the story as the plot.

The catch: Prepon’s divorce record documents dates and legal grounds, but the personal story behind the filing remains untold in verified sources.

Is Laura Prepon still acting?

Yes, but the balance has shifted. Her on-screen output slowed after Orange Is the New Black ended in 2019; the more recent activity has been selective — a spin-off return, some directing, and a book.

Recent and upcoming projects

• Played Alex Vause on Orange Is the New Black, which ran from 2013 to 2019 (Wikipedia biography)
• Appeared in The Girl on the Train (2016) and The Hero (2017) (Us Weekly profile)
• Reprised Donna Pinciotti in That ’90s Show, which premiered in January 2023 (Us Weekly profile)

Us Weekly’s profile summarizes the range: a seven-season Netflix series, two feature films, and a return to the role that made her famous. That ’90s Show brought Prepon back to Point Place, and the premiere made clear the old chemistry with her former co-stars was still there.

Directing and writing

• Directed episodes of Orange Is the New Black and other series (Wikipedia biography)
• Co-authored The Stash Plan, published in 2016; the book reached the New York Times bestseller list (Us Weekly profile)

Prepon’s pivot behind the camera started during her Netflix years, when she directed episodes of the series she starred in. The Stash Plan, a book she co-wrote, gave her a second professional lane entirely outside acting.

The trade-off: Prepon is a harder get for on-screen roles than she was in 2010, because her time now splits between acting, directing, and writing.

The pattern: Prepon’s career has evolved from on-screen roles to a broader portfolio of directing and writing, reflecting a deliberate professional transition.

What is Laura Prepon’s net worth today?

The figure that circulates most often is $9 million — and it should be treated as a celebrity-news estimate, not a court-verified number. Divorce reporting has discussed monthly incomes for both spouses, but those specific amounts aren’t part of the verified material reviewed for this profile.

Estimated net worth

• Estimated net worth: around $9 million (Us Weekly profile)
• Estimate spans television, film, directing, and book income

Us Weekly’s celebrity profile carries the $9 million estimate. By the standards of actors with long network and streaming runs, that number is plausible — but “plausible” isn’t the same as “documented.”

Sources of income

• Acting pay from That ’70s Show (1998–2006) and Orange Is the New Black (2013–2019) (Us Weekly profile)
• Directing fees from episodic television (Wikipedia biography)
• Book royalties from The Stash Plan (2016) (Us Weekly profile)

The income stack is what you’d expect from a three-decade career: long-running sitcom and streaming paychecks, episodic directing fees, and a bestseller’s royalties. The mix is diversified, which is exactly why a single estimate can’t capture the full picture.

What this means: the estimate captures where Prepon sits in the celebrity economy — established, not extravagant. The definitive number, when it arrives, will come from the court record.

Career and life timeline

The dates tell the story; the pattern is a career that keeps finding new formats.

• March 7, 1980 — Born in Watchung, New Jersey (Wikipedia biography)
• 1998 — First major role, cast as Donna Pinciotti on That ’70s Show (Wikipedia biography)
• 1998–2006 — Starred on That ’70s Show, Fox (Us Weekly profile)
• 2001 — Made her film debut in Southlander (Apple TV credits page)
• 2007–2008 — Appeared in ABC’s October Road (Apple TV credits page)
• 2012 — Starred in NBC’s Are You There, Chelsea? (Apple TV credits page)
• 2013–2019 — Played Alex Vause on Orange Is the New Black (Us Weekly profile)
• 2016 — Published The Stash Plan, co-authored (Us Weekly profile)
• 2018 — Married Ben Foster (USA Today report)
• January 2023 — Reprised Donna Pinciotti in That ’90s Show (Us Weekly profile)
• September 9, 2024 — Separation date listed in Foster’s divorce filing (USA Today report)
• 2024 — Foster filed for divorce citing irreconcilable differences (Us Weekly profile)
• 2025 — Continues directing and writing (Wikipedia biography)

The pattern across three decades: every time Prepon’s profile seemed fixed — sitcom star, dramatic actress, author, wife — she switched lanes. The divorce filing is the latest reset, not the first.

Confirmed facts and open questions

What this means: the biographical spine — birth date, roles, marriage, separation — is solid enough to trust. Everything else in the celebrity ecosystem around Prepon, from dollar figures to breakup theories, is provisional until confirmed by the principals or the court record.

What the record says

The people involved haven’t given public interviews that appear in the cited reporting, so the closest thing to direct testimony is the legal record and the outlets that documented it. Three statements capture the public file as it stands.

Foster filed for divorce in 2024, citing irreconcilable differences.

Us Weekly, reporting on Ben Foster’s divorce filing

September 9, 2024, is the date of separation listed in Foster’s court filing.

USA Today, covering the divorce court record

Prepon reprised the role of Donna Pinciotti in That ’90s Show, which premiered in January 2023.

The limitation of the record: it tells you when and how — not why. Readers looking for emotional closure from these documents will leave disappointed; readers looking for dates and legal grounds will find exactly that.

Where Laura Prepon stands in 2025

Prepon enters 2025 with a public identity built on reinvention: sitcom star, Netflix lead, director, bestselling author, and a parent moving through a divorce. The $9 million net worth figure is directionally useful, not definitive; the court record, not the celebrity press, will settle the financial picture. The trajectory suggests Prepon’s next chapter will be written through directing and writing, not tabloid headlines.
