Jennifer Garner caught a flight out of LAX yesterday and a few hours later touched down in Canada. She did a quick change into a black and white dress for last night's Weinstein party thrown at the Soho House Pop-Up Club. Once inside, Jen caught up with her Butter costar Olivia Wilde and mingled with guests like Justin Long, Kate Mara, and Channing Tatum. Tonight, Jen and Olivia will hit the red carpet with their costars at Butter's first premiere. However, Hugh Jackman will likely miss out on the fun while he promotes Real Steel on the other side of the globe. It was just last year that Jen was on hand to join her husband, Ben Affleck, at The Town's TIFF debut, and since then they've gone on to tackle new projects and share the news about their third child.
