The two sisters took to social media on Friday to wish Robert Kardashian well on what would have been his 75th birthday. The attorney and businessman died in 2003 at age 59 after a battle with cancer.
"Happy Birthday dad!!!!! This was my Sweet 16 and this is the moment my dad surprised me with my first car!" Kim shared on Instagram, adding a throwback pic of the memory. "I wish you were here so badly so we could have so many more memories! We are all missing you and celebrating you today!"
The Kardashian family often makes sure to keep Robert's memory alive with posts and recollections of his life, and Kanye West, who lost his mother Donda West in 2007, has empathized with his wife over losing a parent.
