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."
Katy Perry is used to being the one on stage, but on Monday night, she was able to relax to the sounds of a live act other than her own.
The "Teenage Dream" singer took in a show by British indie pop band The xx, who hadn't performed in the U.S. in two-and-a-half years.
Perry, in a large bohemian-style black hat and a floor-length floral dress, hung toward the back of the Fonda Theatre in L.A., where the show was held.
"As her bra strap slid off of her left shoulder, a smiling Katy began to dance around to the band's hit, 'VCR,' " a source tells PEOPLE. "She was with a crew of pals, including her assistant and a few guy friends."
Check in like a superstar!
