The 'Keeping Up with the Kardashians' star had no problem with the 18-year-old model wearing a sheer top without a bra while modelling for Marc Jacobs at New York Fashion Week recently, as the brunette beauty is ''living her dream.''
Asked what she thought about the racy outfit, the 57-year-old Kardashian family matriarch told E! News: ''Well you know, it's Marc Jacob's vision and so you can't really argue with that at all. I was so excited that she was able to walk in his fashion show and more less close New York Fashion Week, and then off to London, so you know she's very professional about it.
''She's such a great girl, has a great heart and she's a good soul, so I don't worry about Kendall.
''She is living her dream. I've got to give her props for really putting in the work. She's got great work ethic and she looks stunning.''
She added: ''I'm so proud of her.''
Kendall and her younger sister Kylie, 16, are set to release their debut fantasy novel 'Rebels: City of Indra, The Story of Lex and Livia' in the near future.
Kris explained: ''They have been writing a book for the longest time. It's going to be released soon and it is really spectacular. I can't even believe my little girls are little authors. It's like a little sci-fi journey.''
Kris was spotted doing a yoga class with her estranged husband Bruce Jenner, whom she split from in October after 22 years of marriage, in Malibu, California on Valentine's Day on Friday (14.02.14), and insisted they will always be close friends.
She said: ''We're terrific. We had a really good time.''
