In the second part of E!'s special About Bruce episode, viewers saw Scott and Bruce speaking openly and honestly about their relationship.
Scott – who has three children with Bruce's stepdaughter Kourtney Kardashian - confessed that he'd always felt insecure about why he and Bruce didn't have a closer relationship.
He admitted (via E!): "I felt like for so many years me and you had a big disconnect and if I would have had any idea of some of the things that you were struggling with, I wouldn't have been so insecure about why we couldn't get along properly."
Scott gave Bruce his full support and added: "It's pretty wild that you're going to live two lives in one lifetime. I mean not many people can say they did it, which is pretty extraordinary in some ways."
Former Olympian Bruce, 65, announced in April that he is transitioning into a woman.
He gave a two-hour interview to ABC News in which he spoke about having gender struggles since childhood. Then, a special two-part episode of Keeping Up With The Kardashians was aired - called About Bruce - which focused on how the Kardashian-Jenner family had reacted to his news.
