"The Celebrity Apprentice": Two celebs fired, Aubrey O'Day walks

(CBS News) Sunday night's three-hour episode of "The Celebrity Apprenice" brought lots of drama, including two firings and one star walking off the show.

The extra-long episode featured two separate challenges - the first was to create a celebrity-styled guidebook of New York City, while the second required teams to create a membership kit for Walk with Walgreens.

During Task 1, Teresa Giudice acted as project manager for Team Forte, while Dee Snider stepped up in the role for Team Unanimous. The winning team was chosen by who raised the most money.

Guest judge Regis Philbin selected the women's book as his favorite, earning them $35,000 towards their fundraising pool. But that bonus check couldn't push them past the men's team, who beat their fundraising efforts by just $14.

Giudice, Dayana Mendoza and Debbie Gibson were brought into the boardroom, and Gibson was fired for raising the least money out of that group (Aubrey O'Day actually raised the least money for the women's team, but she was not brought into the boardroom).

Then, before the second task began, Donald Trump mixed up the single-sex teams. Guiduce, O'Day, Arsenio Hall, Clay Aiken and Paul Teutul, Sr. made up one team, while the other had Lou Ferrigno, Lisa Lampanelli, Penn Jillette, Mendoza and Snider.

Hall and Ferrigno were project managers for this challenge. Though O'Day and Hall butted heads throughout the task, their team's kit was deemed the best. Snider's team was criticized for their poor design, and the Twisted Sister frontman was sent packing.

But the exit everyone was talking about was O'Day's. The former Danity Kane singer said she didn't want to be around the "negativity" and was seen heading for the elevators, which fired stars use when they depart "The Celebrity Apprentice."

Don't expect her departure to be permanent, however - O'Day revealed on Twitter that she stays on the show.
