The final night of the "Dancing with the Stars"' three-night premiere delivered a rock-your-socks-off performance by the fabulous Jonas Brothers! ET caught up with the teen heartthrobs before the big show, where they dished about their new Disney show "Camp Rock," and their excitement having a "DWTS" team dance to their music!

"It's really cool to see them dance to one of our songs because we didn't know what it would be like for somebody to dance to it," Joe Jonas proudly said. "And to see them choreograph it -- it makes you really excited and makes you want to perform a little bit more."

In our new video, ET gets the 411 on Nick, Kevin, and Joe as they talk candidly before their big "DWTS" performance. The Jo Bros may not have done the cha-cha-cha for the judges, but they certainly sang their hearts out at the grand ballroom!

Even though one dancing couple was eliminated in last night's competition and sent home, viewers still got to feast their eyes on the Jonas trio of hotties. Be sure to tune in next Monday night for week two of the power-packed seventh season of ABC's "Dancing with the Stars."
