Kourtney Kardashian Smolders in an Itty Bitty Green Bikini

She's a lean, green, machine! While most of the country shivers, Kourtney Kardashian looked positively sizzling as she strolled the Mexican shoreline in a green bikini on Monday. Kardashian, 34, headed south of the border with longtime beau Scott Disick, 30, and their kids Mason, 4, and Penelope, 18 months, for a little R&R and the reality star hasn't been shy about rubbing it in.
