However, while Kylie, 21, is showing Caitlyn, 69, support, one of the former Olympian’s other children slammed the LGBTQ advocate earlier this month.
During a recent episode of The Hills: New Beginnings, Brody Jenner – who is Caitlyn’s son from his previous marriage to Linda Thompson – revealed that he grew to “not expect too much” from his dad because he was “just never really around.”
Caitlyn is father to Kylie and her older sister, Kendall, 23, from his marriage to Kris Jenner. She is also stepfather to Kris’ children Kourtney, 40, Kim, 38, Khloe, 35 and Rob, 32, from her first marriage to high-profile attorney Robert Kardashian.
She also fathered Brody’s brother, Brandon, 36 with wife Linda, and Burt, 39 and Cassandra, 37 from his marriage to Chrystie Jenner.
