On Thursday night's "Jimmy Kimmel Live!," Jimmy welcomed Kim Kardashian, who was there to promote her new selfie book "Selfish."

However, the reality TV star also discussed her support for her stepfather Bruce Jenner, who recently opened up about being transgender to ABC News.

"Bruce is doing really well," she said. "He is so happy. I think it's the sense of relief from all of the amazing support that he's felt."

"It's a really brave thing to come out and, you know, be so truthful, and to have all of that kind of support I think meant the world to him and our family," Kardashian added.

Last Friday, Jenner, 65, told ABC News that "for all intents and purposes, I’m a woman." He also said that his family has been supportive, and that Kardashian, 34, even offered to give fashion advice during his transition.

"Yes, I said the only thing is, whatever you do, is do not steal my glam team," she told Kimmel to laughs. "They are mine! Like, there are too many girls in this family."

Getting more serious, the "Keeping Up with the Kardashians" star said, "I said, 'Whatever help you need, you have to look and feel your best, so whatever help you need, style-wise, glam-wise, I'm here to help you.'"
