Well, that would explain why she might be stress eating!

According to Star, Tony Romo cheated on Jessica Simpson - in her own bed! The mag reports that just hours after Jess left LA on Janary 16, Tony went to Hollywood hotspot My House, and then threw an afterparty at Jessica's house where he shacked up with a brunette beauty!

Guests partied downstairs, and Tony reportedly took the girl upstairs where he enjoyed "his own private party." A source tells Star, "Everyone was talking about it downstairs. 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."

That would be enough to send me running towards a box of Oreos!
