A sex tape allegedly starring Lindsay Lohan is reportedly about to be made public.

The 'Mean Girls' actress, who recently filmed a documentary about child trafficking in India, is said to be the star of a 47-second clip which could be about to appear on the internet.

A source told the Daily Mirror newspaper: "The video film is dynamite. It is pretty seedy and shows Lindsay engaged in a particular sex act which, obviously, should remain behind closed doors.

"Lindsay was desperate to start 2010 off on a good footing and this is the very last thing she needs. If and when it is released on the internet, via a spurious, unofficial website, there is absolutely nothing she or her lawyers can do about it."

Pornographic magazine Hustler is said to be offering £100,000 for the video, which was filmed by a waiter from a chain restaurant.

The source added: "She is devastated - particularly as she is working hard on cleaning up her act.

"Lindsay has just made a serious documentary on child poverty in India for the BBC, she is terrified this will be put in jeopardy now. It is fair to say that Lindsay has had a pretty torrid past 24 hours."
