Mason Disick, Kourtney Kardashian’s oldest son, got a lot of attention on social media over the weekend. This came as a surprise.

The 13-year-old boy that Kourtney, 44, and her ex-boyfriend Scott Disick, 40, share made a quick appearance in a TikTok video shared by his 10-year-old cousin North West.

Mason tried out a funny dog filter in the video, which added a lighthearted touch to the group of people on Kim Kardashian’s tennis court.

Kim, North, and Penelope, who was 11 and Mason’s sister, went with him. Mason wore a plain white t-shirt and used Kim’s iPhone front camera to take pictures of his pranks.

Their shared TikTok account is interesting because it is closely watched by SKIMS founder Kim, who only lets the app run on her own computer. Mason has a much lower image on social media than his Kardashian-Jenner family members. He rarely posts about his life or makes public appearances.

His public appearances are rare. The last time he was seen on camera was in March, when he went shopping with his dad, Scott, in Los Angeles.

Kourtney is famous for pulling Mason out of her while she was giving birth. She once said that the event was “indescribable and life-changing.”

Even though she and Mason’s dad, Scott, broke up in 2015 after ten years together, they were never married.

As a new phase begins, Mason is about to get a new brother or sister. His mother is currently pregnant with her fourth child.

It will be Kourtney’s first with her 47-year-old husband Travis Barker, whom she married in May 2022.

She told everyone in mid-June that she was pregnant, and at a party last month, they found out that they were having a boy.
