While it has been confirmed that Keeping Up With The Kardashians star Bruce Jenner is set to transition himself from a man to a woman, new reports say his life change is certainly news to some of his children.

Jenner has been rumored to be undergoing the change for nearly a year. But not all of his kids were aware of his decision.

An insider told People Sunday, "There was a lot they didn't know about their dad," particularly referencing his younger children as well as the Kardashian clan.

They added that now that everyone is up to date on Jenner's major alteration, they all stand behind the reality star and famous Olympian. Especially his most recent wife, Kris Jenner. The two were married for 23 years before they finalized their divorce in December 2014. They have two girls, Kendall, 19, and Kylie Jenner, 17, together.

"The number one thing is they all support Bruce. Kris [Jenner] has been great and anything that says the opposite just isn't true. It's really a hard adjustment for her and a shock but she 100% supports him - the whole family does."

Kim Kardashian recently spoke out about Bruce's choice with Entertainment Tonight. Even though she did not confirm or deny the speculation, she made it clear that it is "Bruce's story to tell."

But she did add, "He's the happiest I've ever seen him. We support Bruce no matter what. He should tell his story his way. I think he'll share whenever the time is right."
