Britney Spears shows off bikini body

The happily engaged singer, 30 who is working as a mentor on 'The X Factor', posted a picture of herself on Facebook, Twitter and Pinterest looking like a true California glamour girl, complete with a white bikini, toned body, sun-kissed skin, wind-swept blonde hair and a cool pair of shades, reported People magazine.

"Y'all ready for summer to end? I'm definitely not!," wrote the mother of two alongwith the photo.
