Wilmer Valderrama will make a guest appearance on an episode of the midseason NBC comedy Are You There, Chelsea?, starring Laura Prepon, according to EW.com. The two were co-stars on the Fox hit That '70s Show, which ran from 1998 to 2006.
Valderrama will play Chelsea's boyfriend Tommy, a minor league baseball player.
The show, based on comedian Chelsea Handler's best-selling book, will focus on Chelsea (Prepon) — an opinionated, sexually aggressive young woman. Handler will executive-produce and star as Prepon's older sister.
Valderama will also guest-star on Suburgatory as a guru who provides Chatswin's soccer moms with some spiritual — and sexual — healing. The episode is set to air early next year.
