Britney Spears is one of Elle's January cover girls, an honor she shares with Lady Gaga. Brit's in black and white for the subscribers' version, though inside the magazine she's in bright colors for the accompanying spread. In real life, Brit's just coming off a birthday — she turned 28 yesterday and spent her afternoon out shopping with her boyfriend Jason Trawick. She was also treated to one big birthday present with a Grammy nomination. "Womanizer" is up for the Best Dance Recording against other artists like Madonna and Lady Gaga.
