Are Katy Perry and John Mayer wild for each other – or are they just having a good time hanging with wild animals?
The duo attended a weekend bash at Hollywood talent agent Michael Kives's house, where they were greeted by several special guests: animals from a conservation (including an alligator and a kangaroo!).
"They were really cute," an attendee tells PEOPLE. "They were standing near each other most of the night, playing with the animals outside."
When they weren't checking out the nonhuman partygoers, Perry, 27, and Mayer, 34, "definitely enjoyed each other's company."
