The music star Carrie Underwood, 25, told Allure magazine in the September issue that her college boyfriend Tony Romo is still phoning her although she doesn’t always answer his calls.

Underwood claims their relationship wasn’t serious: "We were both small town people doing very big things, and we relied on each other, dealing with fame," says the singer.

Tony Romo, the Dallas Cowboys quarterback, he is currently with Jessica Simpson who may not find Underwood’s statement very encouraging for her relationship.

She also told the magazine in this quite personal interview: "You never really know why somebody wants to be around you, or if they do genuinely like you. I wish everybody had a label on their forehead so you could automatically tell their intentions."

Carrie has been single for four months now, ever since she broke up with Gossip Girl star Chace Crawford in April. She is blaming her being famous for this. A celebrity never knows whether the ones around he/she are 100% sincere she also explained for the magazine.

She dated Romo from Thanksgiving 2006 to May 2007. She then started to date Crawford from August 2007 to April 2008. Explaining the break up with Crawford, Underwood says "We didn't have a fight. No one cheated. It plain didn't work."

The country pop singer has won five Grammy Awards so far. She was also the winner of the fourth season of American Idol.

She also stated that she had been cheated on but she refused to give any names or other details in support of her statement.
