Kevin, Nick and Joe Jonas won the crowd over with old hits and new songs, but this little gem of a cover of was one of the many highlights of the sold out show.
Nick started things off with the Rihanna cover of "Diamonds" and OMJ, if we couldn't listen to him sing it forever.
Joe and Kevin joined in and it was nothing short of magical...albeit entirely too brief!
Such a tease.
Thankfully, one of the fans in the crowd captured this fab video of the Jonas Brothers singing "Diamonds."
Spectacular, isn't it?
