Lately, the Jonas Brothers have been "Burnin' Up" the charts. The Jonas Brothers, were recently seen on the cover of "Rolling Stone," performed live on "Good Morning America," Friday, Aug. 8.

The "Jo Bros" -- Kevin, 20; Joe, 18; and Nick, 15 -- got their big break last year as the opening act for Miley Cyrus. Kevin plays guitar, Joe sings lead and youngest brother, Nick, is known as the "president" or "musical mastermind" of the band. Cyrus recently admitted to Seventeen magazine that she was "in love" with Nick and that the two now-15-year olds dated for two years.

And these guys are entertainment veterans. Nick was in "Les Miserables" at age 8; Joe, the comedian of the family, was in "La Boheme" on Broadway; and Kevin, "the extrovert," has been in national commercials.
