Kourtney Kardashian was celebrating both of her sons' birthdays on Wednesday.
The reality star shares three children with ex Scott Disick. Their two sons were born on December 14 but are five years apart, with Mason turning 13-years-old and Reign celebrating his eighth birthday. Sister Penelope is 10, with her birthday falling in July.
Reign and Mason were treated to the usual gushing Instagram celebrations by their loved ones, with the famous family lavishing the praise over the pair.
It was matriarch to the Kardashian-Jenner family, Kris Jenner, who was first to wish them a happy birthday publicly. The grandmother, who goes by Lovey to the kids, labelled the pair 'two of the brightest lights in my life' as she shared a series of throwback snaps.
The lengthy post continued: "Mason, you are my first-born grandson, and I am so very proud of you each and every day! You've grown into such an amazing young man, and I adore you."
Turning her attention to Reign, she added: "Reign, you are the funniest!!!! You are one special guy with so many facets to your personality!!!
"Both of you have the most amazing qualities and are kind, considerate, loving, so smart, so talented in so many ways, and such a special magical part of our family …
"AND it's wild that you were born on the very same day!!!! Five years apart!!!! You are both the best sons, grandsons, brothers, nephews, and friends to all of us and I love you so much!!!!!!! Lovey xoxo."
A flurry of fans were also quick to share birthday messages on the post, including Kathy Hilton who uploaded a number of celebratory emojis.
Gemma Collins was among the famous faces to click the like button on the post.
Kris always posts heartfelt messages to her grandkids as she continues her "momager" role in the family.
Following her messages, she also took the time to showcase Kylie's new cosmetics range on her Instagram Story.
Meanwhile, Kourtney, who is now married to Blink 182 drummer Travis Barker, was yet to post her usual birthday montage.
The mum-of-three recently opened up on her hopes to increase her brood with the musician, who has two children - daughter Alabama, 16, and son Landon, 19 - from a previous relationship with Shanna Moakler.
However, she revealed she had felt like she had been 'pushed' into having IVF treatment and is the time to think about her future plans - something Travis, 47, is fully on board with.
