Bitch Stole My Look: Jennifer Lopez vs. Britney Spears

Jennifer Lopez rocked the stage last night at the American Music Awards in an outfit similar to a vintage Britney Spears look. The 42-year-old diva started off singing a medley of her hits in a fierce mini, but by the end of her performance had stripped down to a skintight nude bodysuit with some well-placed sparkles covering her lady parts and sexy strappy stilettos.

Newly-announced mommy-to-be Beyonce glowed in a fiery one-shoulder Lanvin gown that showed off a more regal side to Bey. Her effortless side pony and simple accessories were absolute PERFECTION against her bold dress. But we’re sure Jay-Z already knew that.

MTV Style staple Demi Lovato did not disappoint at tonight’s awards in a silver bejeweled body-con by Mandalay cut to there and metal-toed Christian Louboutin heels. As always, her beauty game was flawless with the perfect shade of nude swiped across her lips and just the right amount of smoky eye – excellent complements to her big-barrel ombre curls.

Selena Gomez? The girl’s style meteor is steadily rising, and this black lacy hi-low hem Julien MacDonald gown paired with gold Brian Atwood heels is another gorgeous well-earned notch to add to her belt.
