Kim Kardashian, 40, shared a tender moment with her sons on Instagram on July 21. The Keeping Up with the Kardashians star was working out in a gym while makeup-free when her oldest son, Saint, 5, and youngest son, Psalm, 2, stopped by for a visit. The doting mother was kissing and cuddling her boys in several cute pics she posted to her page and showed off a workout outfit that included a black crop top, matching leggings, and white sneakers.
