Jessica Simpson and Tony Romo Brokeup Over John Mayer

Tony Romo broke up with Jessica Simpson on July 9 just before her 29th birthday. Jessica did not appear to know a breakup was coming however. On July 2 Jessica wrote a note to her friend Emmy Rossum on Twitter:

"Can’t wait to see your costume on the 10th! Birthday evite coming soon. You are always the best dressed!!!"

Prior to the breakup Jessica and Tony had seen each other last on July 1 when she sang the National Anthem at the National Golf Tournament in Bethesda, Maryland, and Romo played a practice round with Tiger Woods.

After the breakup Tony partied with friends, and Jessica celebrated her birthday quietly with family, and close friends.

On Sunday Jessica wrote on Twitter:

"Everyone needs to know that hope floats … grab the strings and pull it back to you. Falling asleep with my mom and the dogs. Please lord give all of my beautiful fans, friends, enemies, and family rest. Bring all of us peace."

But why did Tony breakup with Jessica if she was so "in love" with Tony. Well …

Another report says Tony looked at Jessica’s phone when he reunited with Jessica on Thursday in Los Angeles, but she got defensive, so Tony looked further. A source said:

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

When Tony saw the messages were from John Mayer the source says:

“Tony dumped her right then. He walked out and that was it.”

That is the smartest decision Tony will ever make in his life. Now if he could just stop dating bimbos.
