Britney Spears Wearing a Bikini | Pictures

Britney Spears wore a bikini yesterday while hanging out in sunglasses. She shared a picture with her Twitter followers along with the caption, "Having some fun in the sun. . . don't want summer to be over!" Britney was able to make the most of the season by taking her sons, Sean and Jayden, as well as her fiancé, Jason Trawick, off for a fun vacation. Last month, the foursome snuck off to Hawaii — and a snap from their getaway made our roundup of the Summer's best celebrity pictures! Despite their fun, the last few months have been full of work. Britney toured the country with The X Factor taping the show's upcoming season, and we'll be able to check her out on the small screen starting Sept. 12.
