With the ritzy MGM Grand Arena acting as the venue, the Diane von Furstenberg dressed "American Idol" alumna star soaked up the spotlight while passing through the red carpet ahead of the annual event's kickoff.
As for what's in store, the Julie Bowen and Ty Burrell hosted ceremony features performances by big names including Justin Bieber, Carrie Underwood, LMFAO, CeeLo Green, Kelly Clarkson, Usher, The Wanted, Linkin Park, Nelly Furtado and Chris Brown.
Meanwhile, Jordin will take the stage as part of the Millenium Award tribute to Whitney Houston along with John Legend.
Of the plans, Co-Executive Producer Richard Beckman said, "I was at the Grammys, and what a curveball they were thrown when Whitney passed away [the day before the show]. They did a good job with Jennifer Hudson, but obviously we had a bit more time, so we wanted to do something honoring such a remarkable performer. We have a lovely segment with a full orchestra and John Legend doing "The Greatest Love of All" -- his voice is just smashing -- and Whitney's last co-star [in the movie "Sparkle"], Jordin Sparks, "Doing I Will Always Love You." And Bobbi Kristina, Whitney's daughter, will accept the Millennium Award for her mother, which we created last year for Beyonce -- that's probably the highest tribute we could pay.
Always one of the hottest nights in music, the 2012 Billboard Music Awards will be getting underway at 8/9c on ABC.
