Amidst his transition, sources tell Us that Jenner has the full support of his 10 children and stepchildren, including stepdaughters Kourtney, Kim, Khloe, daughters Kendall and Kylie, and sons Brody and Brandon.

"They all have become protective of him and just want him to live the way he wants," one insider told Us.

Kim, meanwhile, told Entertainment Tonight in an interview last week that Jenner was "the happiest" she's ever seen him.

"I think everyone goes through things in life, and I think that story and what Bruce is going through, I think he'll share whenever the time is right,” she remarked of his latest transformation. "I feel like that's his journey to talk about."
