Laura Prepon became a household name in 1998 when she stepped into the role of Donna Pinciotti on That ’70s Show, playing the smart, independent, and sarcastic teenage girlfriend who challenged the show’s male leads. The series ran for eight seasons and 200 episodes, cementing Prepon in the memories of a generation of viewers. Born on March 7, 1980, in Watchung, New Jersey, Prepon was the youngest of five children. Before landing the role, she trained in acting and dance and briefly worked as a model in Europe, but she decided that performing on screen was her real ambition.
After That ’70s Show ended in 2006, Prepon avoided the easy path of repeating the same type of role. She took on smaller projects, explored different characters, and eventually landed one of the most significant parts of her career as Alex Vause in Orange Is the New Black. The role marked a clear departure from Donna, presenting a guarded, complicated woman with a far darker emotional world. Prepon also moved behind the camera, directing episodes of Orange Is the New Black.
When That ’90s Show brought Donna back, Prepon returned to the role while also serving as a director on the revival, a detail that signaled her evolution from on-screen performer to creative decision-maker. Beyond acting, Prepon built a second career in wellness and food. She co-authored The Stash Plan, which became a New York Times best-seller, and developed her own culinary products. In 2024, her personal life changed when her marriage to actor Ben Foster ended in divorce.
By 2026, Prepon is 46 years old, but the more meaningful transformation has been professional and personal. She has moved through roles as actress, director, author, mother, and entrepreneur, refusing to let one iconic character define her entire identity. While fans may see someone who looks different from the red-haired Donna they remember, Prepon’s real evolution lies in the breadth of what she has built beyond that single role.
