John Mayer and Katy Perry released their "Who You Love" video Tuesday on ABC-TV's "Good Morning America." In the process, John kind of ripped Katy.

You've heard the song on Channel 95-7, and maybe it's "your song" between you and your significant other.

One thing is clear, the chemistry between John and Katy REALLY shows in the video.

During the interview on "GMA," John slightly dissed Katy when he said she will sometimes play stuff for him in the studio, then he demonstrated his usual reaction by putting his hand over his mouth, and making a face as if he had the heaves.
