Fame Pictures 1 / 8

Lindsay Lohan was left fearing for her life when a man threatened her with a gun on Sunday, breaking down in floods of tears when she realized the weapon was a fake.

The "Mean Girls" star is on holiday in Morocco and went on a shopping trip with friends at the weekend.

But Lohan was terrified to come face-to-face with a gun-wielding man - who she was convinced wanted to kill her.

In a post on her personal Twitter.com page, she writes, "I was walking... with the security guard & some guy was following me, then pulled up in his car and pointed a GUN at me!"

"I was on the phone (with) my mum, I screamed and ducked, the guy started laughing, pushed the trigger, it was a fake gun. I was crying...he scared me."
