Jennifer Garner held onto Seraphina's hand as they picked Violet up from karate class in Santa Monica yesterday. The mom of three is back in LA with her girls after a trip to Las Vegas, where she attended CinemaCon. Jennifer was honored with the female star of the year award and made two hot appearances at the event, which were her first since giving birth to Samuel in February. Jennifer and Ben Affleck have yet to introduce their newest family member, but he is apparently keeping them busy. The couple are just a few of the stars that love the White House Correspondents' Dinner, though it looks like they're skipping tonight's event to be close to home.
