"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," the Sydney Morning Herald quoted a source as telling the Daily Mirror newspaper.
"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," added the source.
In fact, pornographic magazine has put an offer of 100,000 pounds for the video, which was filmed by a waiter from a chain restaurant. "She is devastated - particularly as she is working hard on cleaning up her act," said the source. "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," added the insider.
