Jessica can’t keep her Daisy Dukes on! It’s no wonder Jessica Simpson’s notoriously rocky relationship with Dallas Cowboys quarterback Tony Romo is at risk for a crash and burn. The twenty-seven year old Blonde Ambition actress is cheating on Romo, a scandalous new tabloid tale reveals. Celebrity spywitnesses accuse the oldest of the Singing Simpson Sisters of secretly ho-hopping her way around Hollywood in a series of hush-hush trysts-managing to bed stars like Scrubs star Zach Braff and actor Jared Leto.

“She uses her sexuality as a weapon. She cheated on Tony while telling the world she wanted to marry him,” an insider told The National Enquirer. “And this was happening right under Tony Romo’s nose.”

The National Enquirer blames Jessica’s bitter divorce with first husband Nick Lachey for her unability to settle down with one man: “She’s become a completely different girl since she split with Nick….Right now Jessica doesn’t want to be tied down to just one man,” a friend of the buxom bombshell reported.

According to the report, Jessica had a fling with Zach Braff after the two met at a Hollywood party celebrating Diddy’s star on the Hollywood Walk of Fame:

“They spent that night together and several others,” says a Jess spy. “Then she turned to Jared for several more romantic trysts.”

At one point she was juggling all three guys, The Enquirer says.
