Jennifer Garner  stripes pregnant balet jeans purse kids Violet Seraphina

Jennifer Garner had all three of her babies with her on Saturday -- Violet, Seraphina and the one on the way!

Jen's baby bump is looking bigger every day, and we could really see it as she took Violet to ballet class in Santa Monica!

Garner announced her pregnancy in August, which means she should be due around February.
