We're not sure what the theme of the party was, but Violet and Seraphina sure look adorable!

Over the weekend Jennifer Garner took her two daughters to a pal's birthday bash in Brentwood, and we're guessing hubby Ben Affleck is happy to have her back in town!

Jen spent most of last week in New Orleans wrapping up shooting on The Dallas Buyers Club, and from karate to school, Ben was on double duty with both of the couple's oldest children. Of course, we're sure he's happy to have her back for the holidays and not just because she's usually the one looking after their three kids!
