Rob Kardashian Pops Up on Instagram for the First Time in More Than 6 Months to Honor His Late Father

"Happy Birthday Robert. You would be so proud of our kids and I know you are always with us," wrote Kris Jenner on her Instagram Story

The Kardashian family was full of love and happy memories about patriarch Robert Kardashian Sr. on what would have been his 80th birthday.

Robert was born on Feb. 22, 1944, in Los Angeles and died at age 59 on Sept. 30, 2003 — nearly two months after he was diagnosed with esophageal cancer.

On Thursday, Robert's same-named son Rob was among of the loving tributes.

The typically social media-shy sock entrepreneur, 36, shared a vintage photo of Robert Sr. with his then-wife Kris Jenner. "Happy Birthday Dad! Thank You for giving me only good memories with you. I miss You every day. I Love You so much 💙🥹💙," he captioned the image.

Before that, older Khloé Kardashian shared a birthday post captioned: "I will forever hold space for you. Happy birthday daddy 🤍 I love you 🕊️ thank you for everything 🤍 Every memory. Every lesson. Every laugh. Every ounce of love. Thank you!"

She set a photo slideshow of Rob Sr. to the viral sound called "Hold Space" — which some creators use in sad contexts. "This audio can be viewed as sad or beautiful. I choose beauty. I am not sad anymore," wrote Khloé, 39. "Of course I miss him every single day and wish he were here to meet our babies but I’m not sad. In fact, I feel blessed that I was chosen to have 19 years with the most incredible Man I have ever known."

Kim Kardashian echoed the same sentiments while reminiscing about their ski trips. She shared one of the photos from their memorable vacations on Instagram, writing, "I can’t ski without thinking of you. I’ll always remember the trips and memories you created for us and never ever take those moments for granted. God really blessed us with the most amazing thoughtful, patient, funny, charismatic, loving, and kind dad."

The SKIMS founder, 43, ended the post by sharing that her late dad is "the best example of the purest love."

"He had the best sense of humor and made life so much fun, like every car ride, every meal, watching movies (we had a movie date every Wednesday night, and he would show me an old movie each week)… he made it all so fun and special," she continued. "Happy Birthday to the best Daddy in the world."
