The musical duo is usually pretty shy about showing their love for each other in front of the cameras, but on the cover for their duet, "Who You Love," the couple gives us a little tiny glimpse into their private life.
In fact, John joked that they look like that at home "pretty much all the time."
"'Who You Love' is here. Proud of this song, proud of this artwork, proud of this girl," John posted on his Twitter page.
This was John and Katy's first official couple shoot and some additional black and white shots, taken by photographer Mario Sorrenti, can be seen on Vanity Fair's website.
Recently, rumors have been swirling that John is getting ready to pop the question to his lady love.
Do you think they'll get engaged soon?
