Battle of the Exes: Jessica and Carrie Fight Over Tony

We know Tony Romo is a pretty good catch (hunky, athletic and Latin? sign us up!), but we had no idea the Dallas Cowboys quarterback had the power to cause all-out war between ex-girlfriend Carrie Underwood, and his current flame, Jessica Simpson.

What started off as a series of underhanded jabs between the two (after Carrie made claims that Tony still calls her) has escalated to a whole new level—with Carrie supposedly referring to Jessica as "fat".

Carrie "finds Jessica’s love of putting her life on display pretty desperate," a pal of the singer tells OK! Magazine. "She laughed at the People cover, because it’s the same one Jess did about John Mayer—same smile, same look, except she’s a little fatter.”

Carrie is also confident she has Jessica beat in the talent competition when their albums come out on the country charts together: "Carrie doesn’t think fans will spend money to watch Jess warble through a few badly written songs," says her friend.

While we love us a good old-fashioned catfight, we think these blonde beauties need to retract their claws because all this mudslinging is making them both look dirty. No man is worth fighting this hard for, right girls? Even if he is the star of the football team.
