Lindsay Lohan has fueled speculation she has a new boyfriend, after the actress was filmed kissing a mystery hunk at a Los Angeles restaurant on Friday. The Mean Girls star split up with her snowboarder lover Riley Giles - who she met in rehab - last month, supposedly so she could focus on her career.

But during a night out at Il Sole on Friday, Lohan was filmed by website TMZ.com smooching a dark-haired man whose identity remains unknown.
