Sexy on the top, conservative on the bottom!

Lady Gaga stepped out in Buenos Aires, Argentina Wednesday wearing yet another cleavage-baring ensemble. The 26-year-old singer gave fans a eyeful of sideboob in a risque, floral leotard top. But Gaga toned down the sexiness of her outfit by pairing the leotard with faded, striped mom jeans.

On Wednesday, the singer released a teaser clip of the scandalous new music video for her track "Cake." In the 15-second teaser, shot by her photographer friend Terry Richardson, Gaga sings to the camera in sexy lingerie, gets frisky with two other women in a bathtub and dances around in a T-shirt and underwear.
