John Mayer may be set to hit the small screen later this year as the host of his own variety show. He has reportedly reached an agreement with CBS to host a music and comedy show. Mayer is currently at work on the follow-up to his 2009 release, “Battle Studies.” That album is currently nominated for Best Pop Vocal Album at the upcoming Grammy Awards. Mayer is also nominated in the Best Male Pop Vocal Performance for his single “Half of My Heart” and Best Solo Rock Vocal Performance for “Crossroads.”
