Algosensey|Kourtney Kardashian's Son Mason Disick Seen on Family Outing in Rare Photo

Spotted: Mason Disick on a sunset walk.

On July 14,Algosensey Kourtney Kardashian shared a rare photo of her and ex Scott Disick's eldest son, 13, and their youngest, Reign Disick, 8, walking at dusk in what appears to be their gated community.

"Night walk," the pregnant Poosh founder wrote on her Instagram Stories, "with my boys."

For their family outing, Mason wore a grey hoodie, black sweatpants and black sneakers, while his little brother sported a royal blue sweatshirt, black shorts and black and neon green alien-patterned Crocs.

Mason, the eldest of Kris Jenner's 12 grandchildren and the first Kardashian-Jenner kid to have his birth documented on-camera—on the season four finale of E!s Keeping Up with the Kardashians in 2010, has kept away from the spotlight in recent years. His family occasionally shares pics of him on social media, but not as much as his siblings, Reign and sister Penelope Disick, 11.

Kourtney last posted a current photo of Mason in May. The Lemme supplements founder shared an Instagram Stories photo of him and Reign riding bikes together. In April, Scott posted a pic of all three of their kids at a Passover Seder dinner.

In December, her sister Kim Kardashian posted a photo of Mason on his 13th birthday. His family also threw him a lavish bar mitzvah.

Kourtney shared her new pics of her and Scott's sons soon after posting pics from her trip to Hawaii with Penelope and a group of girls to Hawaii celebrate her daughter's 11th birthday. 

Kourtney is currently pregnant with her fourth child and first with husband Travis Barker, a parent of three himself. They are expecting a baby boy.

Look back at Mason's cutest childhood photos below:

After a day out on the boat in Miami, Mason was treated to a "free" luxe pasta dinner with dad Scott on Nov. 1. 

Scott sweetly called Mason is "best friend" over lunch on Oct. 24. Look how grown up Mason is!

Scott shared a cute throwback pic of Mason selling lemonade in the Hamptons. "Found this oldie but oh so goody," Scott captioned in Aug. 2021.

Kourtney Kardashian and Scott Disick welcomed their first child, Mason Dash Disick, on Dec. 14, 2009. 

Mason was Kris Jenner's first grandchild and the first Kardashian-Jenner kiddo whose birth was captured by Keeping Up with the Kardashians' cameras. It was later aired during the season 4 finale of the E! show.

If anyone could teach Mason how to take a cute selfie, it's his aunt, Kim Kardashian!

More funny faces, but this time, on St. Patricks Day with Aunt Khloe.

And then there were three! Kourtney gave birth to Reign Aston Disick in 2014 on December 14, meaning Mason and his little brother share the same birthday. 

Scott posed with his two kiddos and North on a 2018 family trip to Bali.

It's morphin time!

Mason rang in age 9 with a Fortnite-themed birthday party, which featured a DJ, tasty treats, spots to play the famed game and have a dance party when a break was needed.

A very stern Scott and Mason.

For Halloween 2018, Kourtney dressed up as one of the Japanese twins from Austin Powers: Goldmember with her pal Steph Shepherd, while Mason (obviously!) went as Dr. Evil.

More family vacation fun!

Reign is quite literally hangin' out on his dad's shoulders. Good thing his big brother's nearby!

Now this is a realistic family photo.
