Many of the biggest stars in pop music gathered at the MGM Grand in Las Vegas last night (May 20) for the 2012 Billboard Music Awards. Before making it inside the venue for the big show, which included performances by LMFAO, Justin Bieber, Katy Perry, and Chris Brown, the stars graced the red, erm, white carpet.
Katy, who was honored with a special award for her record-setting and -tying five No. 1 singles from her album, Teenage Dream, matched her purple locks with a sparkly purple dress and strutted the white carpet while flaunting her date, her 91-year-old grandmother. Taylor Swift was a lovely lady in red. Bieber kept it cool and casual (#swaggy!). Carrie Underwood looked like a Disney princess in her big, poofy gown. And Miley Cyrus kept it sexy in a white blazer dress.
Other stars walking the red carpet included John Legend, Alicia Keys, Jordin Sparks, Jason Derulo, Nelly Furtado, Gavin DeGraw, The Wanted, LMFAO, Usher, and more.
