Seriously, you guys. You are not going to want to miss the 2013 Billboard Music Awards. Trust us. It has been announced that Pitbull, Christina Aguilera and Macklemore & Ryan Lewis have been added to the performance bill. This should be one wild party!

The folks over at Billboard couldn't possibly dream up an award show featuring the year's biggest musical acts without Macklemore. He and his producer Ryan Lewis have been the feel-good success story of the year with their single 'Thrift Shop' going to No. 1 with no help of a major label backing them. So we're especially happy they were offered a performance spot in the award show.

Selena Gomez will probably be performing her latest single 'Come & Get It' from her still untitled album, though we wouldn't be shocked if she broke out some new material. X-tina doesn't have any new material coming out, but we'd guess she'll be performing some 'Lotus' tunes.

These three performances have been added to an already stacked bill that includes Taylor SwiftJustin BieberBruno Mars and Miguel. Oh, did we mention Prince will also be taking the stage? Because he is.

Maroon 5, Taylor Swift and fun. lead the pack of nominations with 11 nods a piece with Rihanna notching 10 noms herself.

If you haven't already clear your schedules for May 19 or set those DVRs. It's gonna be a night to remember!

Listent to Selena Gomez, 'Come & Get It'
