Katy Perry and John Mayer shared a ride home from LA's Chateau Marmont on Wednesday night. Recent rumours have suggested that Katy and John are dating, and whether or not they're actually romantic, it's clear the two are pals. John and Katy met up after her recent trip to Brazil to promote her movie, Part of Me. Katy also chatted about the movie in US Elle's September issue. She gave some tips to future suitors, too, which could be helpful for John. Katy spoke about dating and someday marrying again, commenting, "I'm a woman who likes to be courted — strongly. Never say never, I guess you'd say. I'll let love take the lead on that."
