Simpson stressed that her boyfriend Tony Romo does not communicate with his ex, Carrie Underwood, reported UsMagazine.com.
In an interview held on Wednesday (August 20) on Nashville’s 107.5 FM radio, the singer said, "I looked at his call log."
In the September issue of Allure magazine, Underwood revealed, "The phone will ring and it’ll be him, and I’ll maybe not answer."
Simpson retorted, "Tony and I both laughed at that. We got a chuckle out of it."
"If Tony wanted to call her and be with her, he would," added Simpson.
