Kim Kardashian is spending some quality time with her family.

On Monday, the SKIMS founder, 43, shared a few photos to her Instagram which appear to be from this past summer, featuring a rare glimpse of her 13-year-old nephew Mason. In the first photo, Kim carries daughter Chicago, 5, and has her arm around daughter North, 10, who holds up a peace sign and poses for the camera.

The mom of four also included a second photo, which included Scott Disick, 40, and two of his kids, whom he shares with ex Kourtney Kardashian Barker, 44. Scott has his arm around Mason while daughter Penelope, 11, stands in front of her dad and brother.

Next to Penelope, Kim's 4-year-old son Psalm, pictured with his broken arm from the summer, makes a peace sign and holds it in front of his face. He stands in front of Kim, Chicago, North, and the reality TV star's fourth kid, son Saint, 8.

"Everything," Kim captioned the sweet shots.

Scott and Kardashian Barker also share son Reign, 8.

In August, Kim's daughter North shared a video of her spending time with her cousins as they tried out different silly filters, getting her cousin Mason to make an appearance.

At one point in the video, the elusive teen took the phone himself, taking some selfie-style video with a dog filter before passing it back to North.

In a confessional in the season 3 finale of The KardashiansKris Jenner, 67, opened up about her favorite of all the family's moments shared on reality TV — the birth of her first grandson.

"People ask me all the time what was my favorite part in all of our episodes of all of our shows combined, and my answer will always be when Mason was born," she shared.

"Because that was a very special time for me and I was so emotional. And just being in the room when Kourtney was giving birth to Mason, my first-born grandchild. I can't believe he's going to have a bar mitzvah... that thirteen years have gone by since that time. It's just remarkable to me to look back. That feels like yesterday."

During an episode of the Not Skinny But Not Fat podcast in October, Kardashian Barker explained that Mason has expressed he's not comfortable with the spotlight.

"He does not like it. He doesn't want any part of it. He's not on social media," Kardashian Barker explained. "He doesn't love it, and I want my kids to be kids. I crave normalcy as much as we can have it."
