I shaved away my teeth and made them into little pencil points for nice teeth, that's kind of weird if you think about it. I was a notorious teeth-grinder, so all my front teeth became a couple millimeters shorter.

I think that everyone wants sexy hair, and when they think of sexy hair they think of volume - they don't think about flat, limp, lifeless hair. But for some women, it's hard to achieve because we're constantly buying these volumizing shampoos [that] leave a residue in your hair.

I like daytime dates now. By the time night comes, I'm so exhausted and I feel like I'm no fun at night anymore.

If my extensive collection of all 53 Now That’s What I Call Music compilations is any indication, I am both qualified and honored to join Ludacris in hosting this amazing show that spotlights the best music and artists of the year.
