Kourtney Kardashian chowed down on a hamburger while rocking a bright pink string bikini in her latest Instagram post. The Poosh founder, 41, shared a series of throwback pics in a new ‘photo dump’ on May 15, all of which centered around the color pink. The eldest KarJenner sis, who is currently dating Travis Barker, captioned the post “pinkalicious”, and showed off her toned physique as she ate the burger while posing in front of her pool.
