Tony Romo Cheated on Jessica Simpson in Her Bed

Star magazine is reporting that Tony Romo cheated on Jessica Simpson during a party at her house, while Jessica was away:

…that just hours after Jess flew out of Burbank airport on Jan. 16, her boyfriend decided to host a party – at her house! And if that wasn’t bad enough, the hunky quarterback hooked up with a beautiful brunette.

The very night Jessica left town, Tony hit an invitation-only opening of Los Angeles hot-spot My House with a posse that included Laguna Beach’s Stephen Colletti and Entourage star Kevin Connolly. To keep the fun going, he invited a group of revelers "back to my place," the onlooker tells Star. But when people arrived at the two-story country cottage-style home off Coldwater Canyon in Beverly Hills, it soon became obvious that "his place" belonged to his unsuspecting – and absent – girlfriend, Jessica.

Amid Jessica’s gold albums, the party raged on downstairs. But on the second floor, Tony was enjoying his own private party – with a long haired, olive-skinned cutie.

"Everyone was talking about it downstairs," dishes the source. "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."

We wouldn’t be surprised if this was true. Have you seen Jessica lately? She got really fat. The part that doesn’t sound right however, is the girl in the article is a brunette, and Tony likes blondes.
