Caitlyn Jenner may be living as a woman, but she'll always be "Dad" to her children. On Sunday the 65-year-old celebrated her first Father's Day since completing her gender transition in June.

According to TMZ, Jenner spent the day surrounded by her 10 children at her lavish Malibu home. The site reports that, in previous years, it was a struggle to get everyone together, but this year all of the former Olympian's biological and stepchildren cleared their schedules. This gathering was especially monumental because, as TMZ noted, it's not often that the Kardashians and Jenners come together -- especially since Caitlyn (then Bruce) and Kris Jenner divorced in December 2014.

In addition to their special gathering, many of her children shared touching tributes to her on social media. Kylie Jenner posted a photo of her and sister Kendall Jenner with their father, pre-transition. In her caption she shared a sweet quote from Caitlyn reminding her that although her physical appearance has changed, she would always be her father. Kendall followed suit, calling Caitlyn her "hero." Khloé Kardashian was the last of Caitlyn's 10 children to share a Father's Day post, putting up an old photo of a pre-transition Caitlyn and her biological father Robert Kardashian. In her caption she thanked the Lord for the fact that she "was lucky enough to have two" great fathers. Although Caitlyn is not the 30-year-old's actual father, the two have always been very close.

Caitlyn came out as a woman June 1 on the cover of Vanity Fair. Accompanying the glamorous cover shoot was a 22-page spread detailing her journey from male to female and all the trials and tribulations she has faced along the way. While that was the first time Caitlyn officially asked to be addressed as female, she had been very vocal about her transition in the months prior. On April 24 she sat down with ABC's Diane Sawyer for a primetime interview in which she officially announced that she was in fact transgender. Not long after E! aired "Keeping Up With the Kardashians: About Bruce," a two-night special in which the Kardashian family and Caitlyn, who was still going by Bruce at the time, discussed her transition and its effect on each of them. It was in that special that she first told her children they may still call her "Dad," despite the fact that she was becoming a woman.
