It’s always exciting when a bunch of beautiful celebrities gather to celebrate their own, and Audrina Patridge showed up at the 2013 Billboard Music Awards earlier tonight (May 19) in Las Vegas.

And of course the “Laguna Beach” babe was the center of attention as she sauntered down the red carpet outside the MGM Grand Garden Arena ahead of the evening’s affair.

Meanwhile, Avril Lavigne and fiance Chad Kroeger made their mark on the blue carpet, looking more in love than ever.

And while most of the emphasis will be on who wins and what they’re wearing, there’s also a stable full of top acts gearing up to take the stage for live performances.

Among those slated to rock are Lil Wayne, Jennifer Lopez, Chris Brown, Ed Sheeran, Taylor Swift, Bruno Mars, Justin Bieber, Christina Aguilera with Pitbull, and Selena Gomez.
