The 40-year-old DJ documented a night full of pre-NYE festivities on Sunday, December 30, in which Perry, 34 — whom he briefly dated in 2014 — could be seen dancing and sipping champagne.
Eye witness Alexander Hankin tells Us Weekly that Perry and Bloom, 41, “were with Diplo and Kate Hudson at Cloud 9 Bistro on Sunday.”
Hankin added: “The group were all dancing together inside the bistro and spraying champagne. They came as a big group.”
