Jo Dee Messina's new single, "I'm Done," will go for airplay at country radio next week. She is also expected to release a new album, Unmistakable, later this year. In addition, she has reunited with manager Stuart Dill, who represented her from 1997 to 2004, and hired a new public relations company. Messina's previous album, Delicious Surprise (2005), included the No. 1 hit, "My Give a Damn's Busted."
