Britney Spears has been working hard to get in tip-top shape for her X Factor television debut and it appears all of those hours in the gym are paying off.

The 30-year-old revealed her toned figure, by posting a picture of herself yesterday in a white bikini on Pinterest, with the caption 'Y'all ready for summer to end? I'm definitely not!' 

The mother-of-two can be seen proudly showing off her toned mid-section in the playful swimsuit.
