After That '70s Show wrapped up, Rupp continued to grace the stage and screen. In 2012, she starred as sex therapist Ruth Westheimer in the off-Broadway biopic Becoming Dr. Ruth, which earned her a Drama Desk Award nomination for Outstanding Solo Performance.
Her screen credits include a vocal role in the Disney Buddies movie franchise, and she also landed a recurring part in family sitcom The Ranch, which saw her reunite with her former That '70s Show co-stars Ashton Kutcher and Danny Masterson. Most recently, she appeared in the hit Disney+ Marvel series WandaVision, and she’s set to reprise the role of Kitty Forman in That '90s Show later this year.
Rupp, who's now in her 70s, is estimated to have garnered a $5 million (£4.2m) fortune thanks to her long and lucrative acting career.
