Jessica Simpson denies Jenn's claim

We reported that MTV star Bam Margera's ex-fiancee, Jenn Rivell called Friday's "Chio in the Morning" show and said Margera told her that he'd recently slept with married pop Star Jessica Simpson. During the radio call, which can be heard at q102.com, Rivell, said that in an argument with Margera, he told her, "You think you're so f---ing special? I got to f--- Jessica Simpson this weekend, so I can replace you in a minute." "This is absolutely not true," says Jessica Simpson's publicist Brad Cafarelli. Margera's spokesperson offered no comment.
