Father's Day 2015: Kardashian-Jenner Siblings Pay Tribute To Robert Kardashian, Caitlyn Jenner

It was Father’s Day in many parts of the world on Sunday and members of the Kardashian-Jenner clan paid special tributes to the dads in their family. Kim Kardashian West also took the opportunity to confirm that she and Kanye West are expecting a baby boy.

Kendall and Kylie Jenner both took to Instagram to express their love and support for their father, Caitlyn Jenner (formerly Bruce Jenner). Kylie posted a childhood photo with her father and quoted his comforting words of reassurance when he spoke to her about the transition. She wrote: "You can still call me dad, Kylie. No matter what I'm always going to be your father. That's never going to change."

Kendall also went the throwback route and posted a childhood photo with her dad as well. Like Kylie, she touched on the recent transition and commented on the change in Caitlyn’s appearance. She captioned the shot: “My whole life this soul was my daddy and just because your appearance is different now doesn't mean you were any less of a father to me my entire life.”

Khloe Kardashian posted a photo of both men who raised her. Her biological father, the late Robert Kardashian, posed for a photo with Khloe’s stepdad Bruce. She was only 4 years old when her mom married Jenner. She said that she’s lucky enough to have been blessed with two fathers instead of just one.

Kim Kardashian West paid tribute to Robert Kardashian as well by reminiscing about the times she spent with her late father. She then went on to give tribute to her husband Kanye West, father of her 2-year-old daughter North. She confirmed that they are expecting a baby boy. She wrote in her post: “Precious moments like this when we were traveling on tour with you are what I live for. You're such a good daddy to North & you will be the best daddy to our new son too!”
