Ben Affleck and Jennifer Garner threw Violet a party to celebrate her seventh birthday on Saturday in LA. Violet brought her friends for her Build-a-Bear bash, and she was the center of attention in all pink. Among the guests were Jennifer Meyer and her daughter Ruby Maguire. The Meyer-Maguire and Garner-Affleck families also spent Halloween together at an event where both Violet and Ruby were dressed up as Dorothy. Jennifer has been in New Orleans filming The Dallas Buyers Club, though she made the trip back home to be there for her oldest daughter's birthday. Ben is also focused on his three kids — Seraphina, Violet, and baby Samuel — in between the honors that just keep rolling in. Ben was named one of Entertainment Weekly's entertainers of the year, and we'll be seeing just how many accolades Argo will earn when award season nominations kick off soon.
