Rob Kardashian's late father, Robert Kardashian Sr., was on the 29-year-old reality star's mind on Wednesday, when he took some time out to remember him on what would have been the famous attorney's 73rd birthday.
Rob shared two adorable throwbacks of himself with his dad, showing their close relationship.
"Happy birthday pops," Rob Instagrammed alongside a childhood photo of the two with their arm around one another.
"She's an exact copy," he Instagrammed in November, sharing side-by-side pics of the two. "Pops sent us an angel. It's truly a blessing. He's happier than anyone on this day. I'm so happy and thankful."
Robert Sr. died of esophageal cancer in 2003. In November, his former wife, Kris Jenner, and daughters Kourtney and Khloe Kardashian, attended the Angel Ball in New York City to emotionally accept an award on his behalf.
"One of the things he used to teach me and passed down to our children was about philanthropy and about giving and about doing it diligently, constantly, joyfully and generously," Kris said onstage of her ex-husband's legacy. "He taught me and them that no matter what you do in life -- and he would have been very proud of us -- and what you make, you give back and you do it without saying a word."
