Lindsay Lohan's Nude troubles

Beauty Lindsay Lohan's troubles show no sign of cooling off.

According to PageSix, the Mean Girls actress is concerned that nude photos taken of her by Calum Best have been stolen by a computer hacker, and may be published on the web

Celebslam.com claims to have copies of the pictures and is threatening to post them online.

"All I know is that someone broke into my computer and left a file on my desktop saying he got the pictures Cal took from me naked," Lohan says.

Lohan's spokesperson Leslie Sloane Zelnik told the paper, "Anything is possible. I know nothing about it, but her lawyers have been contacted."

A pal told NEWS OF THE WORLD: "Lindsay's furious that naked pictures of her could appear on the net at any moment.

"She's been burned in the past with nasty pics appearing online but she worries she could be the next PARIS HILTON if these pics get out."

Lindsay has had a turbulent time with playboy Calum, who is notorious for taking sex pictures on his mobile as he romps with girls.

In April he was caught on film romping with two hookers in a London hotel.
