The Jonas Brothers joined the plethora of other industry heavyweights appearing at the 2012 iHeartRadio Music Festival in Las Vegas on Saturday (September 22).

The pop trio were dressed to impress, stopping for photos on the red carpet before hopping on stage at the MGM Grand Garden Arena as event presenters.

In an interview prior to the show, the JoBros explained that being at this year’s festival hadn't exactly been on their agenda.

“We got here about an hour ago,” Joe said. "We were rehearsing - we have a show October 11 at Radio City - and we got a call, no joke three hours ago, like ‘hey can you guys come and introduce Enrique Iglesias?’”
