Mason wasn’t the only one of Kourtney andScott Disick’s kids celebrating a birthday on Dec. 14. The teen shares his birthday with little brother Reign, who turned 8. The former couple also shares daughter Penelope, 10.

Last year, Kim praised her nephew over a text exchange regarding her daughterNorth West’s online safety after the then-8-year-old went live on TikTok without permission. In screenshots posted to Kardashian’s Instagram Story, Mason suggested that North be supervised when filming content for social media.

“Hi I don’t wanna disrespect north but I don’t think she should do the lives unless someone is with her because people are always screen recording and she might tell information that isn’t correct and stuff like that, that she will regret,” Mason told his aunt.

“I did the exact same thing as she did. I would do the lives and now I regret saying one of the things that I said,” he continued, adding, “Just in case for safety.”

THAT TIME KIM TAUGHT MASON THE ART OF THE SELFIE

Praising Mason’s actions, Kardashian wrote: “Now Mason is so mature! An insightful king” over the screen grab.

In a second slide posted to her Instagram Story, Kardashian shared her response to her nephew. “I appreciate you looking out Mason And I agree. She felt bad and I don’t think she will do it again but it could be good if you talk to her about it,” the SKIMS founder replied.

Mason agreed, telling Kardashian he would “love” to chat with North, and the reality star then suggested he “sleep over soon.”
