The couple’s eldest children, Violet, six, and Seraphina, three, were attending the martial arts training in Santa Monica, Ca. and RadarOnline.com has photos.
It wasn’t a regular class for Violet who walked in with a white belt and came out with an orange one, proudly clutching a certificate in her hand.
The married A-listers and their kids looked like the picture perfect family, however there was one person missing from their brood – their baby boy, Samuel.
Earlier in the day however Garner, 40, was spotted carrying him on a coffee run with Seraphina.
Affleck, 40 – who is currently starring in Argo – opened up about his daughters’ hobby to talk show host Jimmy Kimmel.
“My daughters do karate,” he said. “I wouldn’t call it a sport as much as I’d call it discipline.
“They know that it’s a way of peace and it’s purely defensive and they would never use their powers to hurt others. But if you tangle with them…they’ll rip your nuts off.”
