Over the weekend, Keeping Up With the Kardashians alum Scott Disick posted a sweet photo of his oldest son, Mason. The two were out to lunch together, prompting the celebrity dad to share a quick snap on Instagram, commemorating the moment. And fans were blown away by just how much Mason has grown recently.
The since-expired photo was shared on Scott's Instagram Story

It looked like a picturesque afternoon on the water when Scott captured the photo of Mason eating lunch surfside. "Just chillin with my best friend," the proud dad captioned the photo of Mason, who seemed to be enjoying the one-on-one time with his father.
Fans just can't get over how old Mason looks in the new photo
It hasn't been that long since filming wrapped on KUWK, but it seems like Mason had a major growth spurt since he last appeared on camera. The nearly 12-year-old looks more like he's about to enter high school than middle school in this latest picture!
Mason is the oldest of the kids Scott shares with Kourtney Kardashian
Scott has three kids with his famous ex-girlfriend. In addition to Mason, the two also have a 9-year-old daughter, named Penelope, and a 6-year-old son, named Reign. Unfortunately for the couple, they famously couldn't make their relationship work and went their separate ways in 2015. Kourtney is now engaged to Blink 182 rocker Travis Barker.
Maybe the father-son duo were soaking up the last few rays of summer sunshine
Mason's 12th birthday is still more than a month away, but with December (and the shorter days of winter) rapidly approaching, Mason and Scott looked like they were taking full advantage of the sunshine during their lunch outing.
Mason doesn't make many appearances on Scott's Instagram grid, so it was nice to catch a glimpse of the boy
Scott doesn't share a whole lot of photos of Mason on social media, so that could be another reason why fans were so surprised by how much older he looked. It's possible that Mason has reached an age where he doesn't want his picture up online that much. Considering he's almost a teen, he's not too far away from having an Instagram account of his own.
Still, we cannot get over just how much older he looks in Scott's recent photos. It seems like just yesterday that he was a tiny toddler.
