Kim Kardashian shared a sweet tribute to her first-born nephew Mason Disick to mark his 13th birthday.
The teen, who tends to stay out of the limelight, is son of the mogul’s eldest sister Kourtney Kardashian and her former beau Scott Disick.
Kicking off the celebrations for Mason’s big day, the Skims founder posted a photo of her stood back-to-back with her nephew as he towered over the 5ft2 influencer.
Both were dressed in casual outfits enjoying the Los Angeles sunny weather when the rare photo was taken.
Kim penned above the image: ‘The day has come where you’re taller [than] me now.
‘I just love who you are and I’m just so proud of you Mason. Welcome to your teenage years. Happy Birthday.’
The megastar wore her long platinum blonde hair down her back and sported a grey Skims robe with black sunglasses and a black backpack.
Her nephew donned a pair of grey tracksuit bottoms, a similar black bag and a white baggy T-shirt.
Mason also covered his eyes with a pair of shades and held a grey sweatshirt over his arm.
He wasn’t the only one to celebrate turning a year older as he shares a birthday with his younger brother Reign.
Reign, who Kourtney also shares with Scott, turned eight alongside his older sibling.
Celebrating their coming of age on December 13, the boys are five years apart in age with Penelope, 10, bridging the gap in the middle.
Kourtney’s famous family were quick to share tributes to the pair of brothers on social media with momager Kris being the first to post her love.
Alongside a collection of throwback posts the matriarch wrote: ‘Happy birthday to two of the brightest lights in my life, my beautiful grandsons, Mason and Reign!
‘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.’
Next, she revealed her admiration for her younger grandson: ‘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.’
The celebrations came after their mother Kourtney shared her relief at re-discovering her energy following 10 months of IVF treatment with husband Travis Barker.
