Earlier this month, Perry, 27, wore a cute little bikini while Mayer, 34, wore a pair of swim trunks as they cooled down in the water, but turned up the heat as they reportedly shared passionate smooches.
“There was major chemistry between them,” a partygoer tells Star. “It was like they were on a honeymoon.”
Reportedly, Mayer kept looking at the Wide Awake singer and at one point, he wrapped his arms around her as he had a smile stretched from ear-to ear.
Another source said, “John and Katy were all over each other. They were holding hands and kissing the entire time. Even in the pool, they stuck together non-stop.”
Now cue the “oohs” and “aahs”… the loved-up couple left the pool party hand-in-hand after hanging out a few hours.
