Bam Margera is at the centre of a sex tape scandal, with racy footage of the star reportedly set to be released on a pay-per-view website.

The Jackass regular, who has previously been romantically linked to Jessica Simpson, is allegedly shown in the tape performing sex acts with blonde Lindsay Hughes, the fiancee of New York radio host Gregg 'Opie' Hughes.

U.S. magazine Steppin' Out reports the tape has been obtained by a former employee of Gregg Hughes, who is now considering taking legal action in a bid to stop the film being published on the Internet.

The publication's Chaunce Hayden tells PageSix: "They're doing the nasty - and I mean nasty. Hughes is taking legal action to prevent its distribution.

"Apparently, he's so distraught, he's banned the name 'Bam' from being mentioned on the (radio) show."

The alleged video footage is sure to put Margera's one-year marriage to Melissa Rothstein under further pressure. Just months into their marriage, in July 2007, Rothstein reportedly gave the star an ultimatum - to quit drugs or end up divorced.
