Kendall Jenner praised her ''hero'' Caitlyn Jenner on Father's Day yesterday (21.06.15).

The 19-year-old model posted a touching tribute to the former Olympian - who was previously known as Bruce Jenner - insisting her recent transition to female doesn't make her ''any less of a father''.

Alongside a photo of herself as a little girl being kissed by Bruce, she wrote on Instagram:

''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.

''Happy Father's Day to the person who raised me, and taught me everything I know, my hero.''

Meanwhile, 17-year-old Kylie Jenner also posted an old picture of herself with Bruce and her older sister Kendall.

Quoting something her parent apparently said to her, she wrote: ''Happy Father's Day my little light of sunshine 'You can still call me dad, Kylie. No matter what I'm always going to be your father. That's never going to change.' ''

And the 'Keeping Up With the Kardashians' star's stepdaughter Khloé Kardashian, 30, found the time to praise both ''phenomenal'' Caitlyn and her late father Robert Kardashian.

Sharing an old photograph of the two, she posted on Instagram: ''Thank you Lord for blessing me with not one phenomenal father but I was lucky enough to have two.''
