Jennifer Garner mom Brentwood

Jennifer Garner is a pro at planning little girl's birthday parties, so she was more than happy to oblige for pal Matt Damon's eldest daughter Isabella's celebration in Brentwood, on Friday afternoon.

The Oscar winner's daughter was born June 11 in Miami, but the family decided to throw her 6th birthday bash this weekend, and it looks like it's going to be a fancy party.

Happy birthday Isabella!
