Jessica Simpson's quarterback boyfriend has been playing away from home, if recent reports are anything to go by.
The Dallas Cowboy reportedly kissed his sweetheart goodbye at the airport before painting the town red with several pals in Los Angeles.
But the partying didn't stop there - Tony allegedly continued to let his hair down at an after party, thrown in Jess' multimillion dollar home.
Onlookers say that the sports star spent most of the night upstairs with a mystery brunette.
"Everyone was talking about it downstairs," a source tells Star magazine.
"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."

Hi friends,
If she wants to keep her man she needs to shed the weight. I'm not even trying to be a bitch, but its the truth. there's tons of beautiful women eyeing tony romo and the chances of him cheating (he's an athlete after all) are pretty high...so she needs to shape up and start taking care of her looks
