Bruno Mars Tweets Excitement About VMA Nominations

Wednesday was a good day for Bruno Mars. The singer/songwriter, who has been on an epic roll over the past 12 months, got some seriously great news when it was revealed that he scored four nominations for this year's MTV Video Music Awards.

The man behind Cee Lo Green's epic hit "Forget You," not to mention hits by Travie McCoy and his own smashes such as "Just the Way You Are" and "The Lazy Song," was beside himself when the news hit, tweeting a series of responses to his first-ever VMA noms.

"VMAs!!!!" he wrote just as the announcements were going out, followed by "4 Nominations!?!?!?! THANK YOU @MTV." He also gave some serious props to the "America's Best Dance Crew" troupe Poreotics, who appeared disguised as monkeys in his "Lazy Song" video, which was nominated in the Best Choreography category.

"YO @POREOTICS - LAZY SONG NOMINATED FOR BEST CHOREOGRAPHY!! #VMAs #MoNKeySwAG!!" he wrote.

He had plenty of reason to celebrate, since the moody, piano-dragging video for "Grenade" is up for Video of the Year, competing against top nominee Katy Perry ("Firework"), Adele ("Rolling in the Deep"), Tyler the Creator ("Yonkers") and the Beastie Boys ("Make Some Noise"). He gave shout-outs to the competition in that battle, saying, "@mtvnews @f---tyler @katyperry @beastieboys Damn!! All great videos!! Congrats to you guys. #SeriousCompetition."

"Grenade" is also in contention in the Best Male Video category, where it will face off against Green's "Forget You," Eminem and Rihanna's "Love the Way You Lie," Kanye West's "All of the Lights," and Justin Bieber's "U Smile."

Mars' fourth nomination is in the Best Pop Video race, where he faces Adele ("Rolling in the Deep"), Britney Spears ("Till the World Ends"), Perry ("Last Friday Night (T.G.I.F.)" and Pitbull ("Give Me Everything").

At the end of the day, Mars just found it all hard to believe. "But seriously?? Who drags a piano across town in some church shoes??? The Brunz does!!! HOOLIGANS VOTE!!!" he encouraged his fans.

The 28th annual MTV Video Music Awards will air live on Sunday, August 28, from the Nokia Theatre in Los Angeles at 9 p.m. ET/PT. See the list of nominees, revisit last year's highlights and vote for your favorites in the general categories by visiting VMA.MTV.com.
