Nick Lachey’s presence at a bachelor’s party last year may cost him wife Jessica Simpson, with a porn star who performed at the night, trying to sell the naughty night’s indepth story to tabloids.

The marriage, which is already on rocks, may end soon if Jessica Jaymes goes public about her raunchy sex acts with two female friends (an Asian and a blonde) in front of Lachey and his friends.

The sexual performance included "whipped cream and sex toys", Star magazine had reported last year. At one point, Lachey got on the bed with the girls and seemed in a trance. But, a male friend of Jaymes intervened and pulled Jaymes away from the bed.

According to the New York Post, Jaymes is reportedly asking one-million-dolar plus syndication rights to the entire story with steamy details. The two other girls and the man who pulled her from the bed are also supposedly going to confirm the story.

Jaymes is also allegedly going to shop a book about the incident. But so far, there have been no takers. The deal has gone out to Life and Style and In Touch, as well as Us Weekly, National Enquirer and Star.
