Jennifer Garner held onto Violet's hand as they headed into a friend's birthday party in Brentwood, and Jennifer was later spotted carrying Seraphina to the car after the fun yesterday. She shielded the sun with a pair of personalized Prada glasses and wore Toms for her latest maternity look. Jennifer has kept her casual style so far during her third pregnancy, but she did get dressed up to promote The Odd Life of Timothy Green last month. She was also in a bump-baring outfit at a screening of her other project, Butter, at this weekend's Telluride Film Festival. Jennifer brought her girls on the trip to Colorado; though, Ben Affleck stayed in LA to work on Argo. He's in the middle of production for the movie, which he's directing and also starring in, and Ben went retro on set just yesterday. Next Jennifer will be off to Toronto for the film festival, where in the past she's supported Ben at TIFF — check out all our Toronto Film Festival pictures through the years.
