Brody Jenner gets along better with Caitlyn Jenner than Bruce.
The former 'Hills' star admits he didn't have the best relationship with his dad, but now the former Olympian has transitioned to a woman, they have grown closer.
Brody said: "I've known Bruce for a long time and I didn't really get along with Bruce - Caitlyn I get along with a little more, because Caitlyn is actually who she really is and she's living her life finally now as the person that she always was."
And the 31-year-old star believes his parent's decision to transition will go down in history.
He told E! News: "What are my thoughts on the transition? It's incredible.I think that it's probably one of the most historical things that's happened in a long [time]."
Brody is delighted to see how much "happier" the 'Keeping Up With the Kardashians' star is since she decided to be her true self.
He said: "Caitlyn is a much freer, happier person and I think that's very special, and I think that the most important thing is that people who are in that situation, don't be afraid to be yourself.
"Be yourself. And if you're not accepted by your family, there will be people who will accept you."
