's 2 ½ month-old daughter Sunday Rose is already learning about life in the spotlight – but she'll also be able to experience quiet family time in Nashville, says pal Ronnie Dunn.
"Nashville isn't oriented [toward celebrity]," the Brooks & Dunn singer told PEOPLE Monday. "It will be more peaceful for them here."
Dunn, who spoke to PEOPLE at a private listening party in Nashville for the soundtrack to the upcoming Billy Graham biopic, Billy: The Early Years,
recounted a text message he recently got from Urban about Sunday Rose.
"He said she thinks that every time they get in a car there's a rubber hailstorm from paparazzi cameras hitting the car," Dunn said. "I offered to fly in a redneck SWAT team!"
Dunn, who duets on the Billy
soundtrack with Mac Powell from Christian band Third Day, says that Urban is loving his new role as dad. "He's eaten up with it," he says. "He sounds very sincere about it."
Urban, 40, himself has said he loves being "Mr. Mom
" while Kidman is working during the day. Currently, mom and daughter are in London where Kidman is rehearsing for the movie musical Nine
. Urban has been balancing family time with traveling for his U.S. tour dates.
