Colin Farrell: Ice Cream with Henry!

Colin Farrell shows off his bulging biceps while out with his son Henry at Baskin Robbins on Monday (August 20) in Los Angeles.

The 36-year-old actor bought his little guy an ice cream cone. Henry kept getting chocolate on his face, and doting dad Colin had a napkin handy to wipe off the ice cream!

Later that day, Colin and Henry stopped at a newsstand, where they bought a magazine.

Over the weekend, Colin was spotted leaving a yoga class shirtless after his workout.

FYI: Colin is wearing a Bouclier Milos tank top. Henry is wearing a Junk Food tee.
