2012 has definitely been Britney Spears' year, as the 30-year-old pop sensation has redirected her career as a judge on the "X-Factor," which many are praising for her gutsy reaction to the contestants. She's also getting into the best shape of her life, which she documented in a recent Twitter photo.
Britney was all smiles as she posed in a strapless two piece bikini in a photo shared to her millions of followers. She added the caption, "Having some fun in the sun... don't want summer to be over!"
