Kourtney 'laughs' off Scott Disick's 'embarrassing' fling with 18-year-old model(photos)

Kourtney Kardashian cracked a rare smile while out and about with her eldest son Mason in Woodland Hills on Saturday.
The 36-year-old reality star dressed her petite 5ft figure in tiny denim cut-offs, peep-toe booties, and a sleeveless Pink Floyd shirt.
The Keeping Up with the Kardashians stunner put on a brave face beneath her large sunglasses and she wore her straight raven locks down.
As they walked inside an office building, Kourtney's five-year-old boy stretched out his arms for a hug from his mother.
The single mother-of-three happily accepted the warm embrace from little Mason, whose spirits have remained up despite his parents' recent split.
The privileged youngster looked cute in his glasses, which he wore with a grey T-shirt, black shorts, and matching plimsolls.
