In an online message board, Lindsay reportedly posted: “All I know is that someone broke into my computer and left a file on my desktop saying they had the pictures Cal took of me naked. My lawyer knows about it.”

“If I ever find out who broke into my computer, he’s in big shit.”

According to a mole: “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’s had a turbulent time with Calum since they first met last year but she’ll be regretting posing for explicit pictures with him.”

“They could be anywhere now.”
