Holy Fez! Wilmer Valderrama is heading back to the future by reuniting with his former That ‘70s Show co-star.

The 31-year-old part-Colombian/part-Venezuelan actor will guest star on an episode of NBC’s midseason comedy Are You There, Chelsea?, which stars Laura Prepon.

Valderrama and Prepon co-starred on the hit comedy series, That ‘70s Show, which aired for eight consecutive seasons on Fox from 1998 to 2006.

Valderrama—who will also guest star on ABC’s Suburgatory early next year—will appear as Chelsea’s boyfriend Tommy, a minor league baseball player.

Based on comedian & E! late-night talk show host Chelsea Handler’s best-selling book, the show will focus on Chelsea (Prepon)—an opinionated, sexually aggressive young woman.

Handler will executive-produce the series and star as Prepon’s older sister.
