The reality TV star took to Instagram on Monday to share a slideshow of images of the basketball player and his children to celebrate him turning 32. Among the snaps, Khloé included some of the first photos of her and ex-partner Tristan's baby son, who was born via surrogate in July 2022. "Happy birthday @realtristan13. You are truly the best father, brother & uncle. Your love, attention, silly dances, hugs, carpool rides, bed time rituals, the way u show up for them.”
