Photographers beware: Lindsay Lohan is fighting mad! Gossip site TMZ reports the “Mean Girls” star was so worked up as she passed a crowd of shutterbugs in front of New York City’s Bowery Hotel, that she hauled off and punched a paparazzo in the nose.

According to an insider, Lindsay stumbled over a barricade meant to hold the photographers at bay and seemed to assume one of the lensmen tripped her. That’s when she allegedly took a swing at a lone pap.

“Oh my God,” LiLo was overheard gasping into her cell phone. “I just hit a paparazzi.”
