Jennifer Garner has no problem praising her husband Ben Affleck although they are in the middle of a divorce. Garner said that Affleck pulled off the ?best dad moment in history? at her son?s recent party. When their son Samuel asked for a superhero party to celebrate his fourth birthday, Garner said he went all out with his costume. She explained that she dressed up as a ninja while Ben dressed up as Batman for Sam. In an interview with Vanity Fair earlier this week, Garner told the magazine that despite their split last summer, their relationship was very real.
