John Mayer

Toto's Steve Lukather brought it onstage weeks after John Mayer played the instrument with Dead & Company.

Guitarist vowed injury wouldn't affect his performance during Sphere residency.

Guitarist segued between the Grateful Dead classic and his 2001 solo hit at recent Chicago concert.

Her song "Dear John" is rumored to be about ex John Mayer.

Is John Mayer missing his ex, or just trying to cash in on the Taylor hype before she comes to Ford Field?

The musicians briefly dated between 2009 and 2010.

From Gwen Stefani to Miley Cyrus and John Mayer, these pop stars have written breakup songs about other famous people.

Why is this not surprising?

The pair were first spotted together in February.

John has been testing out his hosting chops.
