The quick-witted Chelsea Handler is rehearsing for her VMA hosting gig as we speak. The talk-show host caught up with MTV News on Thursday (September 9) to reveal that she's pretty much ready for anything.

"I'm pretty good at answering anything you ask me," she said. "I mean, if I know the answer. If I didn't, I'll just bullsh--. Bleep that please," she laughed. "I forgot I was on a younger person's network."

Speaking of young people, America's favorite teen, the VMA-nominated Justin Bieber, is set to take the stage at the show, and he has quite the past with the comedian. But she admitted that, while he's a "two face" in the love department, she does think he knows quite a lot about it.

"He knows so much about romance," she said. "If you listen to the lyrics of 'Baby, Baby, Baby,' or is it just called 'Baby'? I have to say it three times, 'cause it makes my heart thump. He's obviously been around the block. I mean, I don't know why he's pretending he's not a sexual deviant, because he is."

Handler said she has her guard up these days around the pop sensation after she asked him out on a date only to have him start hanging out with VMA presenter Kim Kardashian instead. "He's using the flirty card with everybody he meets, and I'm not gonna fall for that," she said. "I'm 35 years old. I only have about five good years left in me, and I'm not going to waste my time on that guy."

The 27th annual MTV Video Music Awards will be broadcast live from the Nokia Theatre in Los Angeles on Sunday. The party starts with MTV News' VMA Pre-Show at 8 p.m., followed by the main event at 9 p.m. ET/PT.
