Put on your party dresses, everyone, someone's having a birthday. Only it wasn't, in the photo above, Paula Creamer's birthday. It was tennis player Nicole Vaidisova's birthday, and Paula was there to wish her friend a happy one. The photo is from 2007, and it was Vaidisova's 18th birthday. She has since retired from tennis, suffering (apparently) burnout. Lucky for us that hasn't been a problem for Creamer.
