Caitlyn Marie Jenner (born William Bruce Jenner; October 28, 1949) is an American television personality and retired Olympic gold medal–winning decathlete.
Jenner played college football for the Graceland Yellowjackets before incurring a knee injury that required surgery. Convinced by Olympic decathlete Jack Parker's coach, L. D. Weldon, to try the decathlon, Jenner won the men's decathlon event at the 1976 Summer Olympics in Montreal, setting a third successive world record and gaining fame as "an all-American hero".
Given the unofficial title of "world's greatest athlete", Jenner established a career in television, film, writing, auto racing, business, and as a Playgirl cover model.
Kristen Mary Jenner (born November 5, 1955) is an American television personality, entertainment manager, producer, businesswoman, and author. She rose to fame starring in the reality television series Keeping Up with the Kardashians (2007–present).
She has four children from her first marriage to lawyer Robert Kardashian: Kourtney, Kim, Khloé and Robert, and two children from her second marriage to television personality and retired Olympic Games medalist, Bruce Jenner (now Caitlyn): Kendall and Kylie.
Kylie Jenner is looking more and more like sister Kim Kardashian. The lip kit mogul has been accused in the past of morphing into her older half-sibling, and the comparisons just keep piling up.

While they share the some mother, Kris Jenner, Kim's father is the late Robert Kardashian and Kylie's dad is Caitlyn Jenner, formerly known as Bruce.
They've both lashed out at surgery claims in the past, with Kim once famously having her bum X-rayed to prove it was real and Kylie insisting that she's only ever had lip fillers.
