Kourtney Kardashian’s eldest son Mason Disick made a rare appearance on social media over the weekend.
The 13-year-old — who Kourtney, 44, shares with ex-boyfriend Scott Disick, 40 — had a brief cameo in a video shared to TikTok by his cousin North West, 10.
In the clip, Mason tests out a funny dog filter while hanging out on aunt Kim Kardashian’s tennis court with Kim, her daughter North and his sister Penelope, 11.
The teenager had on a plain white tee as he recorded himself via the front camera on Kim’s iPhone.
The SKIMS founder, 42, monitors the TikTok account that she shares with North and only allows the app to exist on her cellphone.
Mason is the most low-key of all the Kardashian-Jenner cousins as he lacks a social media presence and is rarely pictured out.
He was last pH๏τographed publicly in March while out shopping with his father Scott in Los Angeles.
Mason was featured on his mom’s Instagram Story in July as she informed her following that she was spending time with ‘my boys.’
The pH๏τo showed him walking around their Calabasas neighborhood at around sunset.
Mason rang in his 13th birthday on December 14. He shares a birthday with his little brother Reign, eight, who was born in 2014.
Mason’s parents threw him an epic bar mitzvah in West Hollywood that weekend.
It was attended by grandma Kris, all of his cousins and aunts Kim, Khloe, Kendall Jenner and Kylie.
Kim and Kris penned heartfelt Instagram tributes to the teen on his milestone birthday that included pH๏τos of him through the years.
Proving he’s had a major growth spurt, 5foot2inch Kim shared a pH๏τo of her and Mason standing back to back.
She wrote over the image, ‘The day has come where you’re taller [than] me now.’
Sharing a selfie from when Mason was younger, Kim added: ‘I just love who you are and I’m just so proud of you Mason. Welcome to your teenage years. Happy Birthday.’
Meanwhile, Kris gushed over her ‘first-born grandson’ and how he’s ‘grown into such an amazing young man.’
Mason’s birth was documented in the season four finale of his family’s hit reality TV series Keeping Up With The Kardashians.
Kourtney famously pulled out her eldest son during labor, which is an experience she described as ‘indescribable and life-changing.’
Kourtney and Mason’s dad Scott split in 2015 after a decade together but they were never married.
Mason is about to have a new sibling as his mom is currently pregnant with her fourth child.
It will be Kourtney’s first with husband Travis Barker, 47, who she married in May 2022.
She made the pregnancy announcement in mid-June and learned they are expecting a boy during a gender reveal party last month.
It came over a year after Kourtney made the decision to stop IVF treatment due to its negative effects on her health.
