The late Robert died in 2003 from esophageal cancer. He was 59 years old. Clearly, his memory is never far from the Kardashian family's mind. Last September, Khloe paid tribute to him on the anniversary of his death.
"To the greatest of the great... miss you everyday!" Khloe wrote on Instagram alongside throwback pics with her dad and her siblings, including sisters Kourtney and Kim Kardashian.
