Rihanna's "Diamonds" is hot, hot, hot! The Billboard record-breaking single off Ri's new No. 1 album Unapologetic is stuck in everyone's heads these days, including some of the singer's pop peers.

The Jonas Brothers took the stage with a live, guitar-laden cover of RiRi's hit during their show at Los Angeles' Pantages Theatre this week. Oh, those luscious, brotherly harmonies!

And the JoBros' weren't the only act giving the song a makeover.
