The Valentine’s Day cast toasted their film’s premiere Monday night with a cupcake-filled bash at L.A.’s El Capitan Theatre. Jennifer Garner, who attended without husband Ben Affleck, snagged a few Crumbs cupcakes for her daughters, while Emma Roberts snuck in a sweet treat before retreating to the VIP area with her boyfriend. Jessica Biel held court at a table with three girlfriends, but slipped out early to catch a flight. Also there to party: Bradley Cooper, Taylor Lautner, Eric Dane and Topher Grace.
