New Video: Screaming fans, teary eyes, a joyous ovation: Mass hysteria prevailed as the Jonas Brothers stormed NYC Tuesday for their MTV appearance and concert at the Apple store -- and ET was there! We joined Nick, Joe and Kevin for their rockin' live show at Apple and were with them backstage earlier in the day at their "TRL" hosting gig -- all of which saw a Beatles-esque turnout by their love-struck Manhattan fans!

ET riffed with the ultra-popular bros about their new album, surprises on tour, and their excitement over the fact that Oprah knows their names!
