Kourtney Kardashian Weighs in on Mason Disick's Instagram Launch Years After Shutting Him Down

The first time, which happened four years ago, she shut it down hard, sharing that Mason hadn't told his parents anything about this plan. This time, while she says she's "not OK," the account is still active.

The eldest of the Kardashian sisters shared her eldest son's first post to her Instagram page, captioning it, "My first baby is on insta and I"m not OK." She also tagged Mason in her own share, suggesting she's not only supportive, but offering a little promotional support, too.

That support from his high-profile family is helping, too, as Mason's IG follower count has jumped past 525k in just a few days. He is only following seven accounts: his parents, grandmother, and four famous aunts.

It's official. The next generation of KarJenners is coming online. Aside from North West's shared TikTok account with mom Kim Kardashian, Mason Disick has become the first of Kris Jenner's grandkids to officially take on Instagram solo ... and (presumably) approved.

The page went live Saturday evening with Mason keeping his face hidden in his very first post; a slideshow of two images. The young teen poses for the snaps on a porch overlooking stunning mountain scenery and a lake. He offered no caption.

Almost immediately, though, his aunts had plenty to say, with both Kim and Khloé weighing in with comments. In fact, those are the only two comments present, as the teen's account appears to wisely be limiting comments.

"I can't believe this is happening," wrote Khloé, while Kim added, "You're really on Instagram."

He quickly put up two more posts on Saturday night, mostly focusing on his friends -- and with his face fully visible.

Khloé wasn't quite ready to get over it yet, though, jumping onto her own Instagram Stories to share Mason's first post with a new caption, tagging Mason's page in the process.

"I can't believe my @masondisick is on insta," wrote Khloé. "The one who named us Kiki and KoKo is a legit teenager." She followed with a series of emotional emojis.

This is Mason's second attempt at hard launching his online presence, and at least so far it appears to be sticking. He tried in 2020 when he was just 10 years old on Instagram (and then TikTok), but parents Kourtney and Scott quickly shut it down, revealing they were not aware of it.

As Kourtney explained at the time, it's the comments on social media she was most worried about. "I think on Instagram, the thing that really worries me with kids is just comments," she said on an IG Live at the time. "People can be so mean. It's really easy to get consumed with it. I just feel it's not the time

While the family appears to be supportive of Mason's foray onto social media this time -- and those comments are limited -- Kim has admitted that she's not so sure her own 10-year-old, North, should be on any platform, even though they share her TikTok account.

In an interview with Vogue Italia last year, Kim said, "In a perfect world would they be on social media? No." At the same time, she allows it and shares North's account because her daughter "does not have social media on her phone yet," and will go weeks without it.

But when the moment strikes -- like her viral makeup tutorials using Kim's products -- Kim is happy to share that experience with her daughter. "She just genuinely loves to do videos with me," Kim said. "As things come up, we'll have those conversations."

The KarJenners obviously know a lot about the power and dangers of social media, seeing how they've used the platforms to great success over the years. As Mason takes his first steps into this new sphere of influence, you can bet the whole family will be paying close attention.
