Sexy: Bad Romance 2009 Sexy Scenes

While Lady Gaga is known for completely off-the-wall fashion choices, in her epic video for the hit single "Bad Romance," which clocks in at a decadent five-plus minutes, she looks best when her costumes are minimal. She sports an array of skimpy lingerie throughout and even shows up (technically) nude wearing only a pair of giant go-go boots under a spotlight. But the vid's best moment comes when Gaga drops her white dress (complete with bear-skin-rug train) to show her tiny tush clad in an amazing white lace thong. You'll surely go gaga.
