Jessica Simpson says her boyfriend Tony Romo isn't still calling his ex Carrie Underwood, despite what the "American Idol" winner recently said.

"I looked at his call log," she said Wednesday in an interview with a Nashville radio station.

Underwood told September's Allure magazine that Romo still calls her sometimes, but she doesn't always pick up the phone.

"The phone will ring and it'll be him, and I'll maybe not answer," said the singer of the Dallas Cowboys quarterback.

"Tony and I both laughed at that," Simpson said. "We got a chuckle out of it."

Simpson told September's Elle that Romo "understands" her.

"He appreciates my talent," she said. "He's the first person I've spiritually connected with.”

Simpson dedicated the tune "You're My Sunday" to her beau while performing at a country music festival in Wisconsin on Sunday, saying Romo "is my better tomorrow."
