CBS is close to a deal with pop star John Mayer for a music and variety TV show.

CBS Entertainment president Nina Tassler told a meeting of the Television Critics Association that the project is under development and an agreement is near. She didn't provide details.

Mayer and CBS have worked together before. In 2006, he made a cameo appearance on "CSI: Crime Scene Investigation," performing songs for a scene set in a Las Vegas network.

Mayer, whose current hit is "Say," might also appear on next month's Grammy Awards on CBS: He's up for five prizes. He took the best pop vocal album Grammy in 2007 for "Continuum."
