Scott Disick Calls Son Mason His 'Endless Love' In Birthday Tribute

Scott Disick, 38, is sharing a heart-warming tribute to his son Mason on his 12th birthday. The reality star took to Instagram on December 14 to celebrate his eldest child's special day -- and he posted an old photo of Mason sitting inside the driver's seat of the car. See it below.

The "Keeping Up With The Kardashians" alum added a note to the picture: "My endless love Happy birthday."

Since it's also his youngest son's birthday, Disick also greeted Reign, who turned 7, by posting a picture of him smiling to the camera. He also added a message to the pic: "Nothing better than these boys ❤️ love you more then you could ever know! Happy birthday big guy."

Apart from casually dating several women, Disick has been focusing on his kids, including daughter Penelope, 9, whom he all shares with ex Kourtney Kardashian.

“All Scott talks about is his kids…He’s always bringing them up in conversation when he’s not physically with them," a source told US Weekly.

The insider added, “He’s definitely a very good father and cares and loves them so much. … He wants to be a good role model to them.”

Disick and Kardashian dated on and off for nearly a decade before splitting for good in 2015. Disick moved on with Sofia Richie, whom he dated from 2017-2020. He then dated Amelia Hamlin, and their relationship lasted for less than a year. Kardashian, meanwhile, dated Younes Bendjima from 2016-2018, then moved on to longtime friend and neighbor, Travis Barker, whom she's currently engaged to.

Kardashian hadn't shared any tribute for her sons but has reposted multiple ones from family and friends, including her sister Kim's birthday greeting.

The beauty mogul shared a picture of herself and Mason when he was a toddler and added a note:

"Mason you are so mature and I'm loving who you are becoming. You are so protective over all of your cousins and family. I love you so much and will always be there for you."

The mother of four also shared a photo of herself holding a baby Reign with a message:

"Reign You are the silliest cutest boy in the world! Thank you for being such a best friend for my babies I love you so much and I'm always here for you."

The Kardashian-Jenner matriarch also shared a heartfelt greeting for her grandsons, along with several pictures taken over the years.

"Happy birthday Mason and Reign!!! Can you believe these two were born on the exact same day?! I mean what are the chances???! I will never forget the day that my first grandson Mason was born," Jenner wrote.

She continued, "It will always be such a very special moment in my life because it was really the beginning of my journey as a grandmother. Mason thank you for being the most amazing grandson in the universe! And Reign, you are such a joy! So funny so loving… with such an amazing sense of humor and someone who looks at life with such enthusiasm and joie de vivre!"

The momager added, "You guys will never know how much I love you because words just can’t describe the amount of love I have for you in my heart! Thank you both for being the best grandsons, the best brothers, the best cousins and the best sons to your beautiful mommy My joy in life is watching you grow up and I can’t wait to see what you do next. I’m so proud of you each and every day and I thank God every day for making me your Lovey ❤️???
