New York, May 3 : Talk about fan following. In one of Madonna's recent one-night-only performances, the crowd of about 3,000 got so crazy that a cop pulled his gun and ran after a nutty fan who tried to slip in a side door.
On the night of April 30, the sexy singer was inside Roseland Ballroom to give her performance.
The gig had fans - some of whom slept outside for three days just to get a wristband - so obsessed, they were crying and trying to sneak past the barriers, reports New York Post.
Other officers repeatedly yelled, "Get off the sidewalk!" - but only managed to push fans into honking traffic.
Following her short set that rocked the house, Madonna and Justin Timberlake hit The Box, along with Michael Stipe, Alexander McQueen, Josh Duhamel, Ingrid Sischy, Alex Rodriguez and Donna Karan, who brought her kabbalah teacher.
