A Mayer Home Companion?

CBS is trying to bring Grammy-nominated singer John Mayer aboard to host a music variety show. The Tiffany network and Jennifer Aniston's beau are currently in talks with the singer to negotiate a deal. Network executives hope the show, which would be directed by Grammy producer Ken Ehrlich, will diversify their drama-heavy line-up. Mayer wouldn't be totally new to the small screen--he appeared on CSI in 2006.
