AXEL ROSE IS A REAL G! HE KNOCKS OUT A PAPARAZZI AFTER HE TOLD HIM DONT GET SO CLOSE!

Axl Rose allegedly pulled a Sean Penn the other night and beat up a paparazzi photographer.
The Guns N' Roses frontman -- whose real name is William Bruce Rose Jr. -- punched the snapper after he got too close to a woman in the singer's entourage, reports TMZ.

Before the fight broke out at Los Angeles International Airport Wednesday night, the infamously hotheaded rocker warned the paparazzi to keep their distance.

"Touch her again, I'll break his f---ing neck," he reportedly said while walking through the crowded airport.

Moments later, the woman scuffled with the photographer and, true to his word, Rose hit him, making him fall to the ground, according to TMZ.

The singer allegedly continued to lash out at the man while Rose's entourage attempted to pull him away.

Rose later posted on his band's MySpace page, Myspace.com/gunsnroses, that he "was unhurt last evening when he was accosted by an unruly group of paparazzi."

A member of the National Photo Group who was present during the fight gave TMZ the footage he took of the incident.

TMZ reports that although footage shows two Transportation Security Administration agents observing the scuffle, they never notified airport police.

Rose was reportedly on his way to Taipei, Taiwan, to kick off a Guns N' Roses tour of southeast Asia.
