Britney Spears and fiance Jason Trawick are enjoying a well-deserved vacation in Hawaii with Brit's beautiful two sons, Preston, 6, and Jayden, 5.

The mommy of two Tweeted the above photo and the following, "Happy 4th of July from the Aloha State."

Spears, 30, is currently a judge on the X Factor ... and seems to be lovin' her co-workers. We can't wait to watch our girl on the upcoming season!
