Ben Affleck enjoyed time with two of his kids, Samuel, 9, and Seraphina, 12, on Sunday at Universal City Walk in Los Angeles. 

The 48-year-old actor/director was also accompanied by girlfriend Jennifer Lopez's daughter, Emme, 13, who was spotted munching on snacks and enjoying the sites.

Affleck was dressed casually in dark green pants and a black tee-shirt with the phrase "Don't poke the bear."

The "Argo" star and Lopez, 51, rekindled their romance in April and have been spotted spending time together in different states such as Montana, New York, Florida, and California. They were previously engaged from 2002-2004.
