Nothing like a little sexy on the beach!
PHOTOS: Britney Spears And Jason Trawick Look Ab Fab In Hawaii
The 30-year-old, who took a break from her X Factor judging duties to spend the 4th of July holiday with Trawick and her two boys, Sean Preston and Jayden James Federline, looked flat-abbed and fabulous in a purple and pink string bikini, while her hunky husband-to-be showed off his sensational six-pack in blue swimming trunks.
“Getting ready for some pool time,” Spears tweeted along with a photo of her bikini body flanked by her two sons. “Having a blast xxoo.”
