It looks like things between Katy Perry and John Mayer are heating up.
The pair - who have been spotted stepping out together in recent weeks - are seen here putting on a tactile display at a friend's pool party in the Hollywood Hills.
Katy, 27, cavorted around in a sexy two-piece - while John Mayer, 34, shot her admiring glances, seen in one shot with a huge grin as he wraps an arm around her.
