Lindsay Lohan has been spotted looking cozy with actor Benicio Del Toro - sparking rumours the pair are dating. The teen star reportedly "hooked up with" the 38-year-old actor at a star-studded bash last Sunday. Del Toro was celebrating on/off love Sara Foster's birthday, but "he dumped her to party with Lindsay", according to In Touch magazine.

It's also claimed Del Toro and Lindsay - who has been linked to singer Ryan Adams - spent hours "canoodling". However, Lindsay's representative has said: "She's not dating either of these wonderful men."

Last month, it was revealed the 'Mean Girls' actress had lost her diary - and feared her intimate secrets about her love life could be made public. The star, who recently left $500,000 worth of diamonds in a taxi, was said to have lost the journal during a night out drinking. Although it was later found, some pages believed to contain passages where the 19-year-old candidly writes about her love life and her family problems were missing.

Lindsay's representatives reportedly sent out letters to several leading publications warning them legal action would be taken if any information taken from the missing pages was published.
