Oscar Week Parties: 'Vanity Fair' And 'Interview Magazine' Host Star-Studded Events

Oscar week is in full swing in Los Angeles, and celebrities hit the red carpet for three big industry events on Tuesday, Februrary 22. In the early evening, stars like Pierce Brosnan, Jeremy Piven, and The Social Network's Armie Hammer headed to Eveleigh on Sunset for an event hosted by director Paul Haggis and Vanity Fair. Presented by Briani, the party celebrated Artists for Peace and Justice, an organization dedicated to providing relief to Haiti.

Across town, Vanity Fair hosted another party honoring Wendy Stark Morrissey at the opening of Ray's and Stark Bar at LACMA. Attendees included Suzanne Sommers, Brian Grazer, and Dianne Von Furstenburg. Some stars, like actress Joan Crawford and Mamie Gummer, party hopped between both events, and also made an appearance at Interview Magazine and Hugo Boss' dinner honoring director David O. Russell's Oscar nomination for The Fighter. Other guests included Milla Jovovich, Gossip Girl's Ed Westwick, and of course, Russell himself.
