Kenny Chesney says he is doing "good," months after the breakup of his four-month marriage to Renee Zellweger.

"It's (my heart is) good," Chesney told "Good Morning America" today in his first TV appearance since his much publicized breakup with the star of "Chicago" and "Bridget Jones' Diary." "It's up and down, but it's good."

Chesney also performed from his second new album this year, "The Road and the Radio," which was recorded while he was on tour. Chesney explained that he would have songs faxed to him, sift through the best, and when there was a chance, he and his band would record.

"Anything that's been going on in my life, I usually look to the road or the radio to get me through it," Chesney said.
