Wilmer Valderrama has landed a multi-episode arc on Raising Hope, TVGuide.com has confirmed.

The That '70s Show alum will romance Sabrina's mother Tamara, played by the recently cast Melanie Griffith. In real life, Valderrama is known for wooing younger women (See: Demi Lovato, age 19) but his Raising Hope character has eyes for the 54-year-old Griffith. Further details on his role, first reported by Entertainment Weekly, were not available except that he'll appear in at least three episodes.

In Season 2, Stephen Root played Sabrina's dad. Over the years, the only thing known about Sabrina's parents is that they're wealthy — a stark contrast to her boyfriend Jimmy's slightly more financially strapped family.

Valderrama, who recently starred in NBC's short-lived Awake, has also appeared on Wizards of Waverly Place, Men at Work and Royal Pains.

Raising Hope returns Tuesday, Oct. 2 at 8/7c on Fox.
