Yesterday, JJJ got to hang out with the Jonas Brothers as they taped their MTV special, The Jonas Brothers Experience. You can tune in Monday, February 23 @ 6PM ET/PT.

The show taped at New York City’s 30 Rockerfeller Center (30 Rock), where some of their biggest fans competed for a trip to the worldwide premiere of their new movie, Jonas Brothers: The 3D Concert Experience.

The JB fans caused such a ruckus from jumping up and down, employees up to five floors below the taping thought there was an EARTHQUAKE. Some even evacuated the building and ran down 60 flights of stairs. OMJ!!!!!!!!!!!!!

Things got so bad, security made an announcement on the P.A. system, saying, “Be advised there is no cause for concern. Personnel should not evacuate the building. Event organizers on the ## floor have been notified to keep the noise levels down.”

FYI: There was a tie-breaker question on the show. “Three of the Jonas Brothers concerts took place at NYC’s Madison Square Garden on August 9, 10, 11. What was the total number of fans from all three dates?” Click inside to find out the answer… And don’t forget the JoBros are performing on SNL tonight!!!!
