Is This Hollywood's Happiest Family? Ben Affleck, Jennifer Garner & Their Girls PDA At Street Fair

Ben Affleck and Jennifer Garner took their daughters Seraphina and Violet to a neighborhood street fair on Saturday, and the family had a blast.

While the girls kept busy getting balloon creations from the street vendors, Ben and Jen put on a non-stop PDA.

Ben could barely keeps his hands off his actress wife.  The Argo Oscar-winner was constantly hugging Jen and whispering in her ears.  Jen was all smiles and laughs in return.

The Afflecks are regular attendees at family-oriented events in Pacific Palisades, where neighbors are used to seeing them without bodyguards and without any pretense of fame.

Married seven years, Ben and Jen also have a year-old son, Samuel.
