Her daughter Kendall Jenner also paid tribute to the reality star, posting on her Instagram Story throwback pics of the two, including photos with her sister Kylie Jenner and mom and Caitlyn's ex-wife Kris Jenner.
"Happy father's day to our amazing dad @caitlynjenner," Kendall wrote.
Other celebs also shared Father's Day tributes on Instagram, including Mandy Moore—who posted a pic of her with her dad, Ian Solmerhalder—who shared an image of him with his and wife Nikki Reed's almost 2-year-old daughter Bodhi, and Diane Kruger—who late last year welcomed her first child, a daughter, with boyfriend and The Walking Dead actor Norman Reedus, who has a son from a previous relationship.
