Jessica Simpson is the subject of an X-rated song

Jessica Simpson is the subject of an X-rated song in the new
'Jackass' film, it has been claimed.

The 26-year-old actress was rumored to have had an affair with 'Jackass'
stuntman Bam Margera last year, and now his co-member Chris Pontius has
written a song about their alleged affair for new film 'Jackass: Number Two'

Last year, Bam Margera's ex-girlfriend, Jen, phoned in to the Chico in the Morning Show on Philadelphia's Q102 radio station and she said that a still very married Jessica Simpson, not only had sex with Johnny Knoxville, but that she had sex with Bam Margera.

Bam apparently told Jen this, watching his show on MTV .
.
Now according to the New York Post newspaper, the song is said to describe a
"kinky form of intercourse that can't be printed in a family newspaper".
Although Jessica and Bam have always denied the affair, Bam's father Phil
told a US radio station last May that his son had slept with the 'Dukes of
Hazzard' star.
The DJ asked: "Is Bam nailing Jessica Simpson? Is that what's going on?"
Phil replied: "He's never lied to us, and he said he did."

Bam then admitted he had once shared a bed with Jessica Simpson but insisted he had fallen asleep and nothing sexual happened.
Jessica's spokesman Rob Shuter still insists the pair never had sex.
He said: "There's no truth to it. Bam has been using Jessica's name to get
himself attention for a long time."
