American reality star Kim Kardashian has spoken out in support of her step-father Bruce Jenner's transition to become a woman.

In her first public comments, since the former Olympic gold medalist revealed that he is "for all intents and purposes" a woman, Kardashian said:

"I'm really happy for him that he is living his life the way he wants to live it.

"And that he has found inner peace and just pure happiness. That's what life is about", she told NBC's Today show.

In an interview with ABC's Diane Sawyer, that followed much media speculation he was in the process of transitioning, Jenner said that he had struggled with his gender identity since childhood and did not want to live a lie any more.

He also revealed his family had been very supportive, especially Kim, who has been "most accepting" of his journey to become a woman.

Kardashian also revealed that her family is using therapy to help them better understand and support Bruce as well as each other during his transition.

"I love having so many siblings and such a supportive mom because, you know, each family member might be dealing with this in a different way.

"But we have each other to go through this experience with. And I'm really grateful for that."

Kardashian also said that Jenner was ready for the challenge of helping other people who are going through the same experience as himself.

"That's something that he's really proud of and something that he is really ready to take on. And I'm really proud of him for that", she added.
