Kim Kardashian/INSTAGRAM Kim Kardashian Says Her Late Father Robert Kardashian Would Be 'So Proud' of Her for Studying Law On her birthday last year, Kim was surprised by a hologram crafted in her father's likeness from her now-estranged husband, Kanye West. (Kim filed for divorce from West, 44, this February after almost seven years of marriage.) Sharing a video of the hologram to Twitter, Kim wrote at the time, "For my birthday, Kanye got me the most thoughtful gift of a lifetime. A special surprise from heaven. A hologram of my dad. It is so lifelike! We watched it over and over, filled with emotion."

"Happy Birthday Dad! I celebrate you every single day but today even more," Kim wrote in an Instagram post on Feb. 22. "So much to tell you! I called your cell phone number just wondering if anyone would pick up after all these years. I actually can't believe I remembered it." "Please come visit me in a dream soon. 🙏🏼," she continued. "Also can you pretty please send down a sign in the form of those symbols/birds we always talked about?!?! I just miss you sooooo much!"
