Working hard in the summer while Ben Affleck is on daddy duty at home, Jennifer Garner arrived on the set of "Imagine" in Los Angeles on Wednesday (July 31).

The "13 Going on 30" star looked cute in a dark cardigan, pink pants, and black flats as she got ready for a busy shooting day.

In the dramedy, an old letter written to him by John Lennon and Yoko Ono inspires an aging musician to live life differently, and he sets out to reconnect with his biological son.

Written and directed by Dan Fogelman, the movie also stars Al Pacino, Josh Peck, Annette Bening, Bobby Cannavale, and Christopher Plummer.
