John Mayer Says Collaboration With Katy Perry Is No Gimmick

Katy Perry has beaten her on-again, off-again partner John Mayer to the charts this time around. Both performers have albums out this year, but its Mayer who got to put out the long-rumored duet the two worked on together. With Mayer's latest album, Paradise Valley released this week, and before it hits the market, Mayer wants everyone to know his work with Perry "is not a gimmick."
