Sexy ladies!

While music stars like Taylor Swift and Carrie Underwood covered up in sequined gowns, other hot-bodied celebs were showing some serious skin in racy looks.

Rihanna rocked a black custom Armani design with a plunging neckline, extremely low-cut back and thigh-high slit. "This is a collaboration between Mr. Armani and myself," the star told E! News' Ryan Seacrest. "I wanted something a little bit like Michelle Pfeiffer in Scarface." She topped off her look with sexy black heels and tousled bond curls.

Gwyneth Paltrow, who had the honor of introducing Adele for her evening's performance, heated things up in a Stella McCartney backless halter dress with nude sheer paneling on the sides. She topped off her look with a sleek ponytail.

Anne Vyalitsyna (who was on the arm of her Maroon 5 singer beau Adam Levine) flaunted off her incredible Victoria's Secret-worthy figure in an Anthony Vaccarello mini that showed off nearly everything, thanks a hip-high slit, large, diamond-shape side cutout and plunging neckline. She finished her look with strappy black heels and center-parted beachy waves.
