Ben Affleck: 'I'm the Luckiest Guy in the World'

Jennifer Garner and husband Ben Affleck run some errands on Wednesday (June 27) in Los Angeles.

The couple stepped out with their 4-month-old son Samuel, who was covered in an infant car seat.

Earlier this month, Ben traveled to the nation’s capital to speak at the Child Survival: Call to Action event, which Secretary of State Hillary Clinton also attended.

“I feel like I have a chance to do the most exciting stuff that I’ve done in my career,” Ben recently told the Associated Press. “I’m the luckiest guy in the world.”

FYI: Ben and Jen are using their aden + anais muslin swaddle and Britax infant seat!
