When Hollywood rumors first reported that Katy had been dating John Mayer, we really couldn’t believe it. After all, it was only a few months ago that she was dating Florence and the Machine rocker Robert Ackroyd

But when Katy and John were photographed out on a date in L.A. earlier this month, there was no denying it anymore—they’re definitely going out.

On Saturday night, TMZ caught the new couple leaving a house party together in Los Feliz… and they both got into the same car and drove off.

And get this—John was a total gentleman and even opened the car door for Katy.
