It's official. Famed Indiana rocker John Mellencamp has filed for divorce.

Mellencamp filed the paperwork last Friday in a Brown County court. It was announced last month he and his wife Elaine Irwin-Mellencamp were calling it quits after an 18-year marriage.

The two say they will continue to raise their two teenage sons in Indiana. Mellencamp has recently been photographed with actress Meg Ryan in New York.
