Fastexy:Scott Disick Shares Rare Photo of His and Kourtney Kardashian’s 14-Year-Old Son Mason

Scott Disick knows Mason Disick isn’t always keeping up.

The Fastexydad of three gave a glimpse into his quality time with his and ex Kourtney Kardahian’s eldest son, 14, who fell asleep after their day out. 

“Young blood knocked on the way home,” Scott wrote on Instagram July 23. “Best friend 4 life.”

The Kardashians star shared a picture of him and Mason together in an airplane. Mason, donning a black sweatshirt and sweatpants, turned away and napped in the corner while Scott, wearing a black T-shirt, shades and a gold Star of David, leaned against him.

It’s been an exciting summer for the teen, so it’s no surprise he’s taken some time to recharge. In fact, the former couple’s eldest son graduated from middle school last month. Scott—who also shares daughter Penelope, 11, and son Reign, 9, with Kourtney—celebrated the major milestone.

"Congratulations 2 my best friend in the world," the 41-year-old wrote on Instagram in June, "for graduatiuating [sic] middle school and now on to high school! Let's go mart!!"

Since Mason has gotten older, Scott revealed how much their relationship has developed, too.

"He's great, he's really been unbelievable," the reality star explained during the season five premiere of The Kardashians in May. "We're closer than ever."

More proof that Mason is growing up? He even joined Instagram in May. And the Kardashians couldn’t help but react to the teenager signing up for the social media platform.

"I can't believe my @masondisick is on insta," Khloe Kardashian wrote her Instagram Stories. "The one who named us Kiki and KoKo is a legit teenager."

Meanwhile, Kourtney—who is also mom to baby Rocky Barker, 8 months, with husband Travis Barker—also reflected on his new account, writing on Instagram, My first baby is on insta and I'm not OK."

Now, keep reading to keep up with Mason, Penelope and Reign’s sweet moments over the years.
