Golden rule #1 when you get into a new relationship: Don't bring up the ex! Tony Romo learned that lesson the hard way when he brought up his ex Carrie Underwood to current girlfriend Jessica Simpson while in Hawaii for Pro Bowl.
Romo upset Simpson by making a comment about how Carrie is a better country singer. Well duh...that's a given!
A source said: "He really hurt Jess' feelings. She tried to laugh it off in Hawaii, but she pouted whenever she heard Carrie's songs playing."
The insider added: "Tony said he thought Jess would have trouble winning over audiences with her upcoming country CD."
Since Romo broke the golden rule, this one goes to Jess! She has every right to be pissed off at her new beau for the comment. Do you guys think Jessica's new country album will do well?
