The pair were spotted out Friday night – along with their approximately 15-person-strong entourage – 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 a watchful eye.
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 pals.
They then sat separately at their large table for an evening that stretched past midnight.
