Did Tony Romo Cheat on Jessica Simpson?

It sounds like Jessica Simpson may have made yet another unfortunate relationship choice.

Star magazine reports that the 28-year-old singer/actress’ boyfriend, Dallas Cowboys quarterback Tony Romo, cheated on her earlier this month while she was out of town. The supposed deal went down on January 16, shortly after Simpson departed from Burbank airport.

Left to his own devices, the pigskin-tosser attended the invitation-only opening of Los Angeles club My House, accompanied by Laguna Beach’s Stephen Colletti and Entourage actor Kevin Connolly.

As things wound down at the opening, Romo, also 28, invited a select group of revelers “back to my place”—which actually ended up being Simpson’s home off of Coldwater Canyon in Beverly Hills.

While partyers made themselves at home on the ground floor, a source claims that Romo got cozy with a long-haired, olive-skinned brunette upstairs.

“Everyone was talking about it downstairs,” the mole reveals. “The girls were saying it was so wrong and shady of Tony to cheat on Jessica—especially in her place! I just can’t believe he would hook up with another woman at his own girlfriend’s house.”

Totally. And why should Romo look elsewhere for affection, when there’s more of Jessica to love these days than ever?
