John Mayer and Katy Perry were interviewed on Good Morning America yesterday, listen closely, you might hear John deliver an F-bomb.  (Warning)

 

In the interview, John said Katy will sometimes play stuff for him in the studio . . . and he demonstrated his usual reaction by putting his hand over his mouth, and making a face as if he was about to throw up....

 

 

They also promoted their brand new music video for 'Who You Love', which includes footage of them riding a mechanical bull into the desert.
