It looked like the running of the bulls, except there were no bulls - only tweens.
Thousands of screaming fans stampeded (video below) through the popular outdoor shopping center The Grove in Los Angeles on Saturday to see a free concert by the Jonas Brothers.

Fans lined up for hours before the concert, and when security eventually let them in, it was a free-for-all.
Nick, Joe and Kevin -- who staged the free concert to kick off their summer tour -- played several songs, including their new JONAS L.A. single, L.A. Baby.
The second season of their TV show JONAS has been renamed JONAS L.A. and will premiere on the Disney Channel on June 20. The new season will include guest stars and scenes of the guys running around L.A.
