Dan Gross: Sex tape of Bam Margera a myth?

FIRST the so-called

Marilyn Monroe

sex tape from nearly 50 years ago turned out to be a myth. Now it seems that a sex video said to feature local "Jackass"

Bam Margera

and the Philly fiancee of

Gregg "Opie" Hughes

(of XM Satellite Radio's

Opie

&

Anthony

show) could also be bogus. The

New York Post

's Page Six, quotes

Steppin Out

's

Chaunce Hayden

that a video featuring Margera and

Lynsi

, the fiancee of Opie, is about to surface online. Opie seems pretty confident no such tape exists.

He offered $100,000 on yesterday's show to anyone who could produce a copy of Lynsi and Margera in a sex video. Lynsi's last name is unknown to us, but she went to Drexel and met Opie at a Philly event in 2003. Margera, married to Missy Rothstein, had no comment. Opie said yesterday that he was considering suing Hayden and that the story was based solely on the word of a disgruntled former O&A-show worker, who has been floating the rumor for more than a year. O&A were heard on 94WYSP for a few years until they were fired from the morning slot last October to make room for Kidd Chris.

Out and about

Demi Moore and Parker Posey certainly seem to have hit it off. The actresses, who play sisters in "Happy Tears," which begins shooting in the area next week, have been inseparable since arriving in town Monday.

They picked up a cart full of groceries at Whole Foods (10th & South) early last night.

_ Discovery Channel's "Deadliest Catch" castmates Sig Han-sen and Johnathan Hillstrand hung out at Public House (18th & Cherry) while in town for a book signing the other night. Hillstrand closed down the bar with bartender/manager Katie Doubek over shots of Crown Royal, Jaeger bombs and Irish car bombs.

That Joe Pesci's a fast runner

If you want a glimpse of Joe Pesci running at the Penn Relays, don't miss Central Bucks West's 4x100 meter team on Friday, reports the People Paper's Frank Bertucci. Pesci's a senior at the Doylestown high school and a distant relative of the actor. "Something like third cousins," the younger Pesci told Bertucci. "My grandfather Joseph Frank Pesci and him are first cousins. They grew up together, used to play together," says the high-schooler, who has never met Pesci, but enjoys watching him in "GoodFellas," "Home Alone" and his favorite, "My Cousin Vinny."
