The red carpet at last night's Billboard Awards was chock full of stars ready to get the musical party started. Nicole Kidman, in Dolce & Gabanna, was on hand to show support for her husband Keith Urban, though she was quick to offer a hug to young star Selena Gomez. Selena looked mature in a tight Dolce & Gabanna dress with cutout sides, and the form-fitting outfits kept coming from other celebs like a Mark Fast-clad Nicki Minaj and Ke$ha, in Jad Ghanour. Rihanna, still rocking her red hair, stepped out in an all-white Max Azria suit. Taylor Swift, though, went the sequined route with Elie Saab on her way inside Las Vegas's MGM Grand Garden Arena. It was a big evening for Taylor, who was up for multiple awards. She ended up taking home the honor for Artist of the Year with her album Speak Now and later accepted Country Artist of the Year. There was lots of excitement at the show, including hot sets from Britney Spears and Rihanna — stay tuned for lots of photos from the stage.
