Timberlake and Ferrell in previous SNL visits.

Saturday Night Live will wrap up its 34th season with at least one familiar face.

As revealed during the latest show's promos, Justin Timberlake will bring his sexy back to the long-running sketch show on May 9, marking his third turn as guest host. And Will Ferrell may return to lord over this season's final outing, according to at least one online source.

Timberlake last frequented SNL on November 15, appearing in a skit (and in a leotard/tights) with Beyonce. As a January 2007 co-host, he appeared in the Emmy-winning digital short "D--k in a Box."

R&B singer Ciara will make her debut as musical guest during Timberlake's latest visit.

Ferrell — stripped down to his Hanes and crowing like a man-child, if tradition holds — would emcee SNL's May sweeps finale to promote his summer comedy Land of the Lost. NBC, however, is officially confirming neither his nor JT's (?!) hosting gigs.
