Katy Perry is reportedly on tour with her on/off boyfriend and country singer, John Mayer.
She was spotted on tour with Mayer this week as part of his 'Born and Raised' tour to promote his new album, Paradise Valley, Contactmusic reported.
Although their relationship is all over the place in real life, Perry and Mayer managed to find calm and harmony in their collaborative track, 'Who You Love,' which is a sweet track about realising who you love.
