Britney Spears posted a slightly out of focus image of herself in a bikini on Facebook yesterday with the caption: "Getting ready for some pool time! Having a blast xxoo."

The singer is posing with her two sons, Sean Preston and Jayden James Federline, presumably in a hotel room. She, her kids, and her fiance Jason Trawick are currently on vacation in Hawaii.

The image already has nearly 90,000 "likes" and has been shared by nearly 3,000 users.

Spears is on a break from "The X Factor" auditions, where she's a judge for season two. Fellow judge Demi Lovato is also taking some time off from the show, but was busy performing on "Good Morning America" this morning.
