Kim Kardashian posted a rare family photo featuring her children and husband Kanye West to celebrate Father's Day on Sunday.

The 35-year-old reality star shared a picture of herself with husband Kanye West, 3-year-old daughter North West and 6-month-old son Saint West on Instagram.

"Happy Fathers Day babe! Thank you for always putting our family first and being the best dad to our babies! I couldn't ask for a better husband and more perfect family. We love you so much!" she captioned the snapshot.

Kardashian also paid tribute to her own dad, Robert Kardashian, who died of cancer at age 59 in 2003.

The late attorney was known for serving on O.J. Simpson's defense team during the retired NFL star's 1995 murder trial.

"Happy Father's Day dad! You were the best dad in the world! The last conversation I had with you I told you that I was so lucky to have had the best example of what a dad should be and one day I will have kids and pass on everything you taught me. I'm so lucky to have had you as my dad. I love you," she wrote.

Kardashian and West welcomed North in 2013 before marrying in Florence, Italy, the next year.

Sunday's episode of "Keeping Up with the Kardashians" saw West earn praise from Kardashian's sister Khloe for spending quality time with his daughter.

"Kanye's a really good dad," Khloe told Kim in the episode. "Kanye has great family morals in how he always wants us together ... I love that. It's not at all how I ever imagined he would be."

Sunday's episode also featured Kim, Khloe and Kourtney's reactions to Rob's engagement to Blac Chyna.

The sisters were less than pleased to learn Rob had proposed without telling any of his family members.
