Lindsay Lohan Punched Man For Harassing Sister Ali

LiLo wasn’t kidding when she promised fans a year of “Lohan Mayhem” in 2K10. The actress’ New Year got off to a rocky start after she punched a man for flirting with her kid sister. Lohan was enjoying her holidays on a yacht off the coast of St. Barts with her 16-year-old sister Ali, but the vacation took an ugly turn after the 23-year-old confronted a man who got too close to young Ali during a night out at a local club, Britain’s Daily Mail said Thursday.

“Lindsay repeatedly warned the guy to leave Ali alone. When he didn’t, she viciously punched him. Bodyguards arrived quickly to stop the fight and Ali returned to the boat,” says a spy.

Early Monday morning, Fame Pictures snapped exclusive photos that show Lindsay and Ali crying aboard a yacht while talking on their cell phones.
