Jennifer Garner caught a flight at the Toronto airport in a red cardigan and landed at LAX in a striped sweater yesterday. She was in Canada for the Toronto International Film Festival, where Jennifer premiered Butter with her costars Ashley Greene, Olivia Wilde, and Alicia Silverstone. She also made time to party during her stay up north, and she stopped by The Weinstein Company's soiree and the InStyle and HFPA bash. The pregnant actress got the fun started even before TIFF when she hit the red carpet for the Pink Party in LA over the weekend. Now that she's heading home, though, she'll be able to get back into her routine with her adorable daughters, Violet and Seraphina, while her husband, Ben Affleck, continues working on Argo.
