Listen to Bruno Mars on iHeartRadio

Before Bruno Mars took the stage at the iHeartRadio Music Festival, he gave one lucky fan an extra special treasure

LeeAnn from Salt Lake City, Utah won Bruno's iHeartRadio Music Festival grand prize, listening to KJMY-FM!

Not only did LeeAnn win a trip to watch Bruno at the festival in Las Vegas, but she got upgraded to watch him from a "gorilla"-sized suite, equipped with - as LeeAnn says - "everything you can imagine!"

But that's not all! LeeAnn got to hang out with Bruno before his performance, where he snapped a few pics with her, and gave her tickets to see his show in London! 

Congratulations LeAnn! Say hi to Big Ben, and enjoy the concert!!
