Lindsay Lohan was leaving a nightclub in Arizona with her girlfriend Samantha Ronson when a crazed man pushed past a security guard and lunged at her.
Police and the couple's bodyguards quickly stepped in and wrestled the 38 year old man to the ground.
The Mean Girls star escaped unhurt and told Police that she did not know the man. He was later arrested for disorderly conduct.
Nightclub owner Dan Wierck said:
"The gentleman became very excited when he realised he was so close to Samantha and he has a history of being a stalker with Lindsay Lohan so he immediately attacked her and started yelling, 'I love her, I love her!'"
