Ben Affleck & Katherine Schwarzenegger Casually Walk Past Each Other Unnoticed!

Ben Affleck and Katherine Schwarzenegger walked past each other on the sidewalk in Brentwood, California on Monday morning, March 18.

The 46-year-old actor and the 29-year-old daughter of Arnold Schwarzenegger and Maria Shriver didn’t seem to notice each other as they crossed paths.

Ben looked healthy and happy as he walked along the sidewalk in a dark blue jacket, light blue shirt and a casual pair of jeans.

Katherine was casually dressed in an all-black ensemble complete with leggings and a sweater and engrossed in a chirpy conversation with her gal pal.
