'Celebrity Apprentice': Aubrey O'Day's blond again and Dayana Mendoza has no love for Lisa Lampanelli

the-celebrity-apprentice-live-finale-nbc.jpgDuring the two-hour live finale for "The Celebrity Apprentice" on NBC Sunday (May 20) night, Donald Trump welcomed the previously fired contestants to the stage (minus Cheryl Tiegs and Michael Andretti, though his dad, Mario Andretti, did drive Donald Trump to the live show) -- including Victoria Gotti, George Takei, Tia Carrere, Patricia Velasquez, Lou Ferrigno, Dayana Mendoza, Aubrey O'Day, Lisa Lampanelli, Teresa Giudice, Dee Snider, Penn Jillette, Lisa Lampanelli, Debbie Gibson and Adam Carolla.

Find out who won "The Celebrity Apprentice."

Here are a few things we learned:

- Lou had surgery for his hearing impairment. "For the first time in my life I can hear without a hearing aid," he tells Donald.

- Dayana has nothing positive to say about Lisa, but Lisa thinks Dayana's crying impersonation of her was hilarious. "I think she's great," Lisa says about Dayana. "I love being made fun of. I dish it out and I can take it."

- Aubrey's blond again!

- Teresa doesn't think she's naive. "If anything, I'm a little too trusting and I try to see the good in all people," she says.

- Dee has had two surgeries on his hand, which he broke during the show, but it's still looking a little wonky.

- Victoria thinks Aubrey is "a cartoon character" and she thinks Lisa is "just crude, rude and classless."

- Penn thinks Clay Aiken should win.

Do you agree with Penn? What do you think of Aubrey's blond locks?
