Aubrey O'Day, Clay Aiken Join 'Celebrity Apprentice'

Reality TV certainly isn't anything new for Aubrey O'Day or a bunch of her other just-announced castmates on the latest installment of "Celebrity Apprentice." On Wednesday (January 4), it was announced that former Danity Kane singer and MTV's "Making the Band 3" star O'Day will be joined by a who's who of reality stars and musicians, including "American Idol" season two runner-up Clay Aiken.

Racecar driver Michael Andretti, TV and radio personality Adam Carolla, actor Lou Ferrigno, former talk-show host Arsenio Hall, magician Penn Jillette, rocker Dee Snider, "Star Trek" actor George Takei, "American Chopper" star Paul Teutul Sr., actress Tia Carrere, singer Debbie Gibson, "Real Housewives" castmember Teresa Giudice, Victoria Gotti of "Growing Up Gotti," comedian Lisa Lampanelli, model and actress Cheryl Tiegs, Miss Universe Dayana Mendoza, and actress and model Patricia Velasquez round out the cast.

The celebrity winner will earn $250,000 for the charity of their choice. "It's hard to top the last few seasons, but we think we've done it," the show's host, Donald Trump, told The Hollywood Reporter about the cast. "We didn't want to change much. We're not looking to reinvent the show in its 12th season. I think we have a great, very diverse cast. It's amazing the abuse they take and the kind of work they put in."

In season 11, the group of celebrities that battled it out for supremacy was just as diverse, including folks like "Real Housewife" NeNe Leakes, Lil Jon, Sugar Ray singer Mark McGrath, classic rocker Meat Loaf, La Toya Jackson, R&B legend Dionne Warwick and country star John Rich, who won the show.
