Kim Kardashian Shares Rare Pic of Baby Saint on Father's Day -- While Caitlyn Gets Boxed Out!

"Happy Fathers Day babe!" the mother-of-two captioned the sweet snap above. "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!"

In the family pic, the "Keeping Up With the Kardashians" star is on a surfboard near the sand as hubby Kanye West carries 6-month-old Saint towards the water. Meanwhile, North, 3, is seen from behind in an adorable white bikini.

Not only did the rapper feel the love, but Kim also gave a shout-out to her late father, Rob Kardashian.

"Happy Father's Day dad! You were the best dad in the world!" she captioned a throwback Instagram pic of the two. "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. In so lucky to have had you as my dad. I love you."

It seems she forgot to celebrate her stepfather, Caitlyn Jenner, though!

In a video on Kylie Jenner's SnapChat, the "I Am Cait" star revealed that her youngest daughter was the only member of the famous family to invite her over yesterday.

"Ok, there it is, my favorite daughter right now," Cait said in the clip. "Why? Because it's Father's Day, and she's the only one who invited me over."

Oops!

Kylie also posted a tribute to her father on her website, sharing an adorable flashback photo in honor of the holiday. "Happy father's day to this incredible soul," she wrote. Kendall and Kris Jenner also honored Caitlyn on their Instagram pages as well.

Caitlyn also took to her account to give a shoutout to all the "different families out there."
