Coming straight from a rainy M83 concert at Coachella, Katy Perry arrived at 2 a.m. with six male pals at the Hennessy V.S. Presents Details @ Midnight party.
A seemingly upbeat Perry, who showed off newly dyed purple hair, ran inside the bash to dance and mingle with the crowd. And a source tells us that her late arrival kept the festivities going until 4 a.m. – past the scheduled end time.
And a long night out didn’t stop the pop star from having enough energy to hit the party circuit the next day; she made her way during the mid-afternoon to the Lacoste L!ve/HTC Pool Party at a private home in Thermal, Calif.
