Katy Perry John Mayer set trailer rollers couple dating filming house home John Mayer Katy Perry love nest

On Tuesday morning John Mayer was seen leaving Katy Perry's brand new Hollywood Hills house and going to a studio, and a few moments later Katy flew out the door and headed to work. X17 photographers snapped Katy on set with rollers in her hair, and she was in a very upbeat mood. Looks like someone had a good night!

The two were first reported to be back together when Katy had a Memorial Day bash at her new pad last week, and Us Weekly reported that the lovebirds "were very flirty and having a really good time together. They have good chemistry."

The duo first started dating in the summer of 2012, they broke up that August and then they got back together again in September, only to split again in March. Third time's the charm?

P.S. Lovin' the rollers in her dark locks!
