Some of the performers slated for the 2012 Billboard Music Awards have been announced, and oh this lineup is gooood! Justin Bieber is set to perform at the event, which will be held Sunday, May 20. So will LMFAO, the Wanted and Carrie Underwood. What a mix!

The Biebs is gearing up to mark the live debut of his new single ‘Boyfriend’ on ‘The Voice’ season finale, which is on the calendar for May 8; so he will follow that up with his perf at the 2012 Billboard Music Awards, which will rock the MGM Grand Grand Garden Arena in Las Vegas to its rafters, and air on ABC at 8PM.

The Biebs and LMFAO teamed up at  the 2011 American Music Awards, so maybe they will reprise their party rocking? Maybe he’ll rock with the Wanted? Anything is possible. But, one thing is for certain: PopCrush will be tuning in and covering every single that happens at the event. What happens in Vegas won’t stay there, if we have anything to say about it.

It’s going to be a fun night in the music industry on May 20.
