Katy Perry: Death Becomes Her

The singer celebrates turning 24 with a pre-Halloween costume party

Leave it to Katy Perry to celebrate her birthday with dead people.

The always-kooky “I Kissed a Girl” songstress marked the big 2-4 with a pre-Halloween costume bash last night at Siren Studios.

Guests were asked to come dressed as their favorite dead celebrity. Perry’s costume? Freddie Mercury, the late lead singer of Queen.

The deadly theme started with Perry’s arrival to the bash in a hearse.

Inside, the more than 200 guests, including Josh Groban and Cisco Adler, were treated to a game of bobbing for body parts, a coffin photo booth and an execution chamber. Perry's cake was in the shape of—what else?—a dead body.

Among her gifts was a 10-karat Rosette Button pendent with rubies and diamonds from famed jeweler Pascal Mouawad.

Party host Malibu Rum served specialty drinks, including the Mercury (in honor of Ms. Perry’s drag king costume), the Monroe and the King.

The festivities died down at about 1 a.m.

Perry wasn’t the only one celebrating a birthday last night. Ne-Yo toasted his 28th with a MasterCard-sponsored party at the Whiskey at the W Times Square. Guests included Busta Rhymes, Christina Milian and Vivica A. Fox. At the end of the evening, the man of the hour was presented with a bottle of Hennessy Paradis, a 150-year-old cognac.
