Rihanna looked like the living embodiment of her colorful "S&M" video in her Dior Haute Couture gown. A rainbow of colors including purple, turquoise and lime green, the dress was shocking and yet incredibly feminine thanks to tulle and bow detailing.

Avril Lavigne proved she's still all punk rock in her little vintage Julien Macdonald black dress. The dress' frilly bottom was complemented by a sequined top. Lavigne accessorized the look with her signature colored streaks and heavy, smoky eyes.

Adele went for ladylike chic on the carpet in her cocktail-length black dress. Cheryl Cole donned a sophisticated floor-length, backless gown by Stella McCartney that was amped up with sequins.

Eliza Doolittle went to the Rihanna school of fashion for her look. The pop singer graced the red carpet in a short, white, sleeved dress that seemed pretty dull until she turned around and exposed the plumage of multicolored fringe on her derriere. Newcomer Jessie J looked goth in her open-toe ankle boots and super-short green satin dress. She wore it with super-heavy smoky eyes and deep red lips.

The guys also showed off their personal styles. Justin Bieber donned his signature black leather jacket, black pants and skinny black tie. Mark Ronson looked chic in a tailored sharkskin suit complete with skinny tie and white shoes. And leave it to Cee Lo Green to say "f--- you" to all the rules of red-carpet style. He wore a bedazzled tracksuit to the show.
