Elle Magazine, the No. 1 fashion magazine in the world, threw a party to celebrate their new July 2010 “Women in Music” issue (with Rihanna on the cover) at the Highline Ballroom Wednesday (Jun 9) in New York City.

Some of the celebrity attendees at the inaugural event were Cassie, Kelis, Patti Labelle and Roc Nation artist Alexis Jordan. Both Patti Labelle and Kelis treated guests to performances later in the evening.
