The IMG Models holiday party at Gilded Lily in Chelsea on Wednesday night looked like a high school dance because, “Male and female models were totally split — guys on one side, girls on the other,” a guest reports.

Spotted were beauties Emily DiDonato, Jules Mordovets, Xiao Wen and Hanne Gaby Odiele, fotog James Macari, IMG’s Ivan Bart, Victoria’s Secret’s Ed Razek and Susanne Bartsch. Singer Natalia Kills performed and Jeffrey and Erik Tonnesen DJ’d for the agency, which celebrated the same day it was acquired by WME.
