Los Angeles - Kim Kardashian West has thanked her step-father Bruce Jenner for teaching her "so much about life".
The 34-year-old star took to her Instagram account to post a nostalgic black and white picture of the pair together and wished him a happy 65th birthday on Tuesday.
Kim's sister Kourtney Kardashian, 35, also took to the social networking site to praise the former track and field star - who split from their mother Kris Jenner last year - for being an "inspiration" to her.
She posted a throwback picture of the ex-sportsman in the USA kit with one of his decathlon medals.
