It’s always a party when LMFAO is in the house and the producers of the Billboard Music Awards grabbed RedFoo & Skyblu, Justin Bieber, The Wanted and Carrie Underwood to perform at this year’s event.

While the MGM Grand Garden Arena in Las Vegas will be filled to capacity with superstars and artists alike on May 20th, these acts are set to rock the house like never before. Justin Bieber is expected to perform ‘Boyfriend’ and with his partnership with LMFAO at last year’s AMA’s being such a success, maybe they will hit the stage again this year (Possibly treating us to a surprise appearance of Far East Movement and joining in for the LMFAO remix of ‘Live My Life’).

Adele, LMFAO and Rihanna are leading this year’s nominations with Adele racking up 18 nominations including Top Artist, Top Female Artist and Top Billboard 200 Artist. LMFAO comes in second with 17 nominations and Rihanna following behind with 13 nominations.

The show will be broadcast live on Sunday May 20th at 8 PM ET on ABC.
