Jennifer Garner in a Red Gown at the NYC Premiere of Butter

Jennifer Garner made a red-carpet appearance with the cast of Butter at the NYC premiere last night. She chose a strapless Gucci gown for the occasion, which came after attending a press conference earlier in the day. Jennifer had Ashley Greene; Olivia Wilde, in Alexander McQueen; and Ty Burrell by her side for both events. Costar Alicia Silverstone missed out on this afternoon's promotional stop but joined them for this evening's screening and later at the afterparty sponsored by Appleton Estate Rum. Jennifer, Alicia, and Olivia mingled with Harvey Weinstein at Double Seven, where they celebrated their premiere.

While Jennifer is working in NYC, her husband, Ben Affleck, is on the West Coast. He attended a charity dinner on Monday night and was spotted grabbing lunch on his motorcycle yesterday.
