Britney Spears has a body that just won't quit! The 30-year-old mama of two showed off her bikini bod while striking a pose at her LA estate.

Along with the photo, Brit Tweeted: "Having some fun in the sun. Don't want summer to be over!"

The engaged songstress will soon be heard on an upcoming will.i.am track. The Black Eyed Peas singer Tweeted that he's "still putting the finishing touches" on the song. He added, "Britney's part is dope."

Britney's X Factor will premiere on September 12.
