Chesney still upset over Renee split?

Kenny Chesney is still heartbroken over his split from Renee Zellweger - and is using his music to help him get through the difficult time in his life.

"It's like medicine - and obviously I need that now," eecho.ie quotes him as saying. "What was that old song? 'We got married in a fever, hotter than a pepper sprout.'"

The country singer married Zellweger in May this year, but Renee filed for an annulment four months later amidst rumours that he had been too controlling.
