LAST PRANK I PULLED

I do little ones all the time. When my makeup artist is doing my makeup, I like to scare her when she is really focused. I jump back in my chair, and she freaks out. It's actually not very smart because it can totally mess up what she's doing.

LAST TIME I BONDED WITH BRITNEY SPEARS

At The X Factor's boot camp [audition], during breaks we'd sit behind the panel and use the paper on the table to play tic tac toe and doodle.

LAST TV SHOW I WATCHED

CNN Newsroom. I always watch CNN. I'm kind of a nerd like that.

LAST THING I COOKED

I hate cooking. The last thing I made was a cup of coffee.

LAST TIME I EXERCISED

I went running on the beach, and then I did a little meditation afterward and put my feet in the water.
