jaleel white gi 'House': Jaleel White (yes, Urkel) locked up for guest roleThe season premiere of “House” in October will feature a former child star in a rather grown-up role.

Jaleel White, who’s nearly 35 now but will probably be forever known as Steve Urkel from “Family Matters,” will guest-star in the Season 8 premiere, a FOX rep confirms to Zap2it. (White’s casting was first noted by TVLine.)

His role? Prison inmate. “House” begins its season about a year after the events that ended last season, with House (Hugh Laurie) doing some time in prison. White’s character will also be doing time and will presumably cross paths with the doctor.

(Bonus Jaleel White casting news: He is also set to reprise a guest role on “Psych” in the fall, TV Guide reports.)

Post-“Family Matters,” White starred in the sitcom “Grown-Ups” and guested on “The Game” and “Boston Legal.” He also starred in and executive produced a web series called “Fake It Till You Make It,” which aired on Hulu last year.
