Perry and Mayer talking romance
Katy Perry and John Mayer have been chatting about their relationship in a joint TV interview.
Roar singer Katy compared her love life to riding a bull during the chat on Good Morning America.
"Relationships are kind of like riding a bull. You hang on for dear life," MailOnline quoted Katy, 29, as saying.
"Sometimes you get a little buck here and there and sometimes you get things thrown at you but you get back on."
Katy and John, 36, made the TV appearance to show off the video for their duet Who You Love.
John admitted he jumped at the chance to work with his girfriend in order to see her.
"I had to [make] a video in order to get to see my girlfriend," he said.
The couple admitted they were worried about how to act in the interview, with John saying: "We don't quite know what kind of body language we're supposed to be exhibiting.
"You get too close it's a little too touchy feely and you get too far away and people say 'I don't see chemistry'."
John said recording a song together was a risk.
"It's a pretty big moving target to be a couple and have a song but there's an authenticity to it," he said.
Katy said of their first date: "We just went to dinner as a regular couple. We share music as a love together. That's a common interest."
