Kim Kardashian Instagram Story. Kim Kardashian/Instagram Kourtney Kardashian's Son Mason Disick, 14, Joins Instagram, Shares Rare Photos of Himself All Grown Up On Saturday, May 25, Mason — whom Kourtney Kardashian Barker shares with ex Scott Disick — launched his first official Instagram page. The teenager shared rare photos of himself looking all grown up on the social media platform, having declined to be on social media throughout the past few years. In his first post, Mason uploaded a photo of him posing outdoors on a balcony with his head dipped down, wearing a cap over his face, a black T-shirt and khaki green baggy pants. In a second snap, he turned his back to the camera as he showed off his outfit some more. Mason received emotional reactions from his aunts Kim and Khloé Kardashian in the comment section as they responded to the photos. “I can’t believe this is happening,” Khloé, 39, wrote as Kim added, “You’re really on Instagram 🥹.” On her Instagram Stories, Khloé again shared her reaction to the teen joining Instagram, expressing her shock at how old Mason was getting. "I can't believe my @masondisick is on insta. The one who named us KiKi and KoKo is a legit teenager," she wrote over the first photo Mason had shared on the platform, adding several emotional emojis. In March, Mason showed off his designer outfit on Khloe's Instagram Stories, which included multiple pieces of Chrome Hearts jewelry. The video began with the Good American founder filming Mason's brown motorcycle boots, slowly panning up to show that he was wearing jean shorts and a matching jean jacket. "Fit check, Chrome, Chrome, show me your belt, show me the belt, yes, Mason," Khloé said. Mason then put his fists together to show off his jewelry. "Oh, fit check, let me see these rings," Khloé said. "What is happening? Chrome! Chrome! Chrome!"
