The 'I Am Cait' star - who was previously married to the sock designer's mother Kris Jenner - is impressed with the way her troubled stepson has turned his life around since meeting fiancee Blac Chyna, making more public appearances and seeming to be more at ease with himself.

She told 'Entertainment Tonight': "You know, everybody goes through tough times in their life and deals with a lot of different things.

"I always look at it as 'Everybody has their stuff,' you know? It's how you deal with your stuff, and how you come out the other end."

Rob is expecting his first child with Chyna - who also has three-year-old son King Cairo with ex-boyfriend Tyga - and Caitlyn couldn't be happier for him.

She added: "Things are going well."

Caitlyn joined Diane Sawyer at the GLAAD Media Awards at the weekend, where they accepted the Outstanding TV Journalism award for the veteran broadcaster's tell-all '20/20' interview with the former Olympian before her gender transition, when she was still known as Bruce.

And the 66-year-old star admitted her "biggest concern" with the interview was how her children would react to it.

Accepting the award, she said: "I have 10 children. My biggest concern was my kids, especially my last two, little Kendall and Kylie [Jenner] who are 17 and 18 at the time.

"And of course I do live in the most social media family, by far, and I got Kourtney, Kimberly, Khloe [Kardashian], Kendall, Kylie, everybody's there on the couch. And they can reach about 250 million people, and they've all got their phones, going 'Oh my God, look at this comment, look at this comment!'

"It has been quite a ride for the past year. And there is nothing better in life than living your life authentically."
