When paparazzi caught LeAnn Rimes and hubby Dean Sheremet shopping Sunday in Malibu, one photographer took the opportunity to ask their thoughts on the supposed rivalry between Jessica Simpson and Carrie Underwood. After playing coy, Rimes finally weighed in on Tony Romo -- Simpson's current boyfriend and Underwood's former flame.

"That's hysterical," Rimes told TMZ of the "fight" over the Dallas Cowboys quarterback. "I'm sure he's enjoying every minute of it. Any man in their right mind would enjoy two hot women ... there ya go."

When the photographer praised Rimes and Sheremet for their drama-free marriage, the singer had a simple explanation: "We're boring. We're not in high school anymore."

Before the couple could escape the cameras, the pesky paps got in one final question, asking Rimes if she thinks Simpson can be the next Dolly Parton.

"She's got the assets already," Rimes responded, laughing. "She's got one thing going for her!"
