Kourtney Kardashian's son Mason Disick joins Instagram and fans notice same thing

Kourtney Kardashian's eldest son, Mason, has made his Instagram debut and fans can't help but notice the striking resemblance between the 14 year old and his famous mum.

Mason, who is Kourtney's firstborn with ex Scott Disick, has only shared three snaps on his new account so far. Despite being known for shying away from the limelight, he seems to be enjoying sharing moments with his mates.

The account has been active for less than a day and already boasts a whopping 128,000 followers. However, it seems Mason has restricted who can comment on his posts, with only two comments visible so far - both from his A-list aunts, Khloe Kardashian and Kim Kardashian.

Fans are going wild over Mason's Instagram debut, with many pointing out his uncanny resemblance to Kourtney. One fan penned on Reddit: "He looks so much like Kourt! " Another echoed: "Looks like a mini Kourtney," reports the Mirror.

Fans have been doing a double-take over how much Mason Disick, the once small child from the family's reality show, has changed now that he's hit his teen years. Comments are flooding in like: "Mason looks so different. I didn't even recognize him."

While another chimed in with, "its boys, throughout their lives they look like 5 different people especially from childhood through puberty to 20s. its mad lol."

And there's love for his resemblance to mum Kourtney as one fan gushes, "I never realised how much he looked like kourtney! " Meanwhile, someone else is feeling nostalgic, adding: "He's a cutie! It feels so wrong he's a teenager already. He was born like, yesterday lol."

But it's not just his looks that are getting attention eagle-eyed fans have spotted something intriguing about Mason's Insta habits. One fan notes: "Interesting. He follows all the Kardashians, but not his stepdad."

Another echoes the sentiment, saying: "This instagram has me so confused. he's 14 he should have one if he wants, but he's only following the karjenners, no friends. I feel like this is the launching of Mason as a famous person and not his personal insta? idk, he's a kid i don't know so i'm staying away."

It's not Mason's first rodeo on Instagram either. Four years back, he had an account that went live, dishing answers to fan questions before it swiftly turned private and disappeared.

Back then, Reddit users were quick off the mark, spreading the word about the ten year old's social media move, but it wasn't long before the account vanished.
