In addition to becoming one of country's most successful recording queens, Jo Dee Messina has reportedly taken up songwriting as well. One of her tunes entitled "Hero" is being considered as a recording by both LeAnn Rimes and Martina McBride. Plus! It was only a matter of time before Messina followed in the footsteps of several fellow country artists. Messina heads out to San Francisco, California, later this month to film an episode of CBS' Nash Bridges, starring Don Johnson. The Messina-featured episode airs April 30th.
