Everyone is still talking about the Tony Romo/ Jessica Simpson break-up and they are super angry that the guy would ditch her on the eve of her 29th Birthday. But there is some juicy gossip that keeps on leaking out about the couple that turns out to be not to perfect.

Apparently, even after Jessica and John Mayer broke up in 2006, the two remained close.  Too close for Jessica’s own good.

Radar is reporting that Tony found messages from John in Jessica’s phone.  He had just flown into LA on Thursday, one day before Jess’ 29th birthday when he found the messages.

The source says, “They were hanging out and he picked up her phone and she got defensive about it. Tony found messages from John and went ballistic.”

That was apparently the straw that broke the camel’s back, because according to the source, “Tony dumped her right then. He walked out and that was it.”

Guess Tony doesn’t like playing those types of games.  I don’t know why Jess would do something like that.  Tony was the best thing to happen to her since her divorce.
