Lindsay Lohan has a stalker, a male fan who sends her letters giving her his name and phone number and begging for them to meet up.

According to reports, the same person has been sending bunches of flowers to the 20-year-old star on the set of her new movie Georgia Rule.

A memo has been posted on the gate where the film is being made which reads: "One of our actresses has a stalker."

The alert comes just weeks after Lindsay revealed she had a fan who was pursuing her.

She said at the time: "He says he's going to be at the Chateau Marmont before my birthday and prove to me that we're meant to be together, even if he has to take me away and teach me. They have a picture of him there. It's scary."

Meanwhile, Lohan is planning to pay a visit to US troops in Iraq.

She said: "I've been trying to go for so long.

"I'm not afraid of going. My security guard is going to take me to a gun range when I get back to Los Angeles, and I'm going to start taking shooting lessons."
