The Oscars are Sunday night at 7/6c on ABC, but the parties have already begun! Vanity Fair hosted two big soirees last night in Hollwood, each to celebrate one of the nominees for Best Picture—and also support good causes! The cast of Les Miserables—InStyle cover girl Amanda Seyfried (in Dior), Man of Style Eddie Redmayne, and nominee Anne Hathaway, who were all joined by Isla Fisher, wife of castmate Sacha Baron Cohen—celebrated together to support the Los Angeles Fund for Public Education. Meanwhile the cast of Silver Linings Playbook, including nominees Jennifer Lawrence (in Roland Mouret) and Bradley Cooper, attended a party that raised funds for The Glenholme School, a boarding school for children with special needs.
