Her feature film career is on fire, having earned an Oscar nomination for co-writing Bridesmaids and starring soon in pics like Girl Most Likely, Despicable Me 2, Anchorman: The Legend Continues and The Secret Life Of Walter Mitty. Vampire Weekend will be the musical guest for her show. Affleck, whose Argo won the Best Picture Oscar this year, will host for the fifth time for May 18′s season finale, with Kanye West as musical guest. The show already revealed that Zach Galifianakis will host May 4 with musical guest Of Monsters and Men.
