On-and-off couple Katy Perry and John Mayer were spotted partying along with their 15 friends at West Hollywood's Chateau Marmont.
The group was ushered into the far back corner of the tented patio and took their place at a cluster of tables, with servers and security keeping an eye on them, reported People magazine.
Mayer, 35, wearing a dark shirt under a grey fitted blazer, shook hands with everyone, while Perry, 28, looked stunning in a short-sleeved white 50's style cashmere sweater and a fitted metallic patterned shirt as she chatted with their friends.
Perry and Mayer called it quits after a second time.
"I'm on the same journey as everyone else. Coupling is a tricky thing." Mayer had said.
