What do you do when you're Oprah Winfrey, you're ending your mega-successful show in about a year and you want your audience to surge during the May sweeps? First, you get Tom Cruise to return to your program. Then, you fill in around that.

That's exactly what Oprah is doing on her show. On the May 14 installment Cruise, along with Cameron Diaz, will show up to promote their upcoming action-comedy 'Knight and Day.' Don't look for too much couch-jumping by Mr. Cruise, though, as he has a movie to promote.

Surrounding Cruise's appearance are a bevy of personalities, both in and out of Hollywood, that will stop by to chat with Miss O. This includes Simon Cowell, Dolly Parton, former First Lady Laura Bush, Julia Roberts and, for all of you screaming teenage girls out there, Justin Bieber. The full schedule can be found after the jump.

May sweeps is here, bringing with it season or series finales chock full of weddings, deaths and cliffhangers galore. Wondering when your favorite show ends? Get the full 2009 May sweeps schedule.
