The invitation that has popping up in users' inbox exists in several variations (many misspelling her name), including "This is 'Lindsey Lohan's Just leaked Celeb Sex Tape','This is Lindsey Lohan's Having a THREEWAY on Camera', and 'Lindsey Having Sex with HOT Girl'.
Once users open the invite, the message reads "Do not ask how I got this video. No one has seen this sex tape except for the people invited to this event (And seriously guys…DONT tell anyone that I posted this…ESPECIALLY anyone in the media!)"
However, Lohan's pals told TMZ you won't see the star naked – at least, not this way. Instead, if you try click on the link, it's likely you'll get a computer virus. According to her friends, the Mean Girls actress is aware of the invite and insists no such video exists.
The 24-year-old does have access to a computer in rehab, but whether or not she uses her time to go on Facebook is unclear. "She only has one hour of Internet access per day and she is using this to stay in the loop with her family and friends while trying to do some career stuff too," the New York Daily News quoted a source as telling Radar Online.
Facebook and Lohan's manager did not immediately return requests for comment.
