UPDATE: Kelly Clarkson, Usher, Linkin Park and Nelly Furtado have been added to the lineup. This is a Top 40 music fan's wet dream.
Justin Bieber, Carrie Underwood, LMFAO and British-Irish boy band The Wanted have been confirmed to perform at the Billboard Music Awards on May 20 at MGM Grand Garden Arena in Las Vegas.
Adele leads all nominees with 18 (?!) nominations, including Top Artist, Top Female Artist and Top Billboard 200 Artist. LMFAO, Rihanna, Lil Wayne and Lady Gaga all picked up double-digit nominations.
Award organizers have promised more announcements in the coming weeks. Last year, the show featured performances by Beyonce, Pitbull, Nicki Minaj, Lady Antebellum, the Black Eyed Peas, Rihanna and Britney Spears, among others.
