Kourtney Kardashian & Scott Disick’s Sidewalk Kiss (PHOTOS)

Kourtney Kardashian and beau Scott Disick left baby Mason at home for a shopping trip in New York’s Soho on Tuesday, sharing a very-public sidewalk smooch.

Mason isn’t always left out of his parents’ retail therapy — just last week he accompanied mom on his first trip to the grocery store.
