Brian Austin Green went for an NYC stroll with his son, Noah, yesterday. He took the 6-month-old, who wore a knitted monkey hat, out in SoHo and stopped at an Adidas store during the outing. Noah's already becoming quite the traveler, having visited Brazil with his parents last month. Brian and Megan Fox celebrated Carnival, but Noah skipped out on the festivities. The family has since been lying low, though Megan will soon get to work on Ninja Turtles with producer Michael Bay.
