People Magazine reports:

“Following dinner at Ago, the group headed to XS nightclub, where they sat in a VIP table. Perry, wearing a sparkling black cocktail dress and miniature top hat with a veil, sat with Rihanna, remaining low key, sipping Grey Goose.

Later, the group headed to Sapphire strip club. There, Perry was spotted checking out the female dancers who danced to her songs, and she even got a dance of her own from a blonde dancer before the group headed to a private skybox – away from the public’s eye.”
