THE Pussycat Dolls star KIMBERLY WYATT studied dance at New York's JOFFREY BALLET before showing off her sexy moves as a performer on Royal Caribbean cruise cabaret shows. The DON'T CHA singer admits life on an ocean wave was far from fun - because she suffered from seasickness and couldn't wait to hit port. She explains, "I knew I wanted to quit after my first ship, because I get so seasick, and I was on the toilet every Friday."
