Los Angeles - Caitlyn Jenner is "proud" of Rob Kardashian.
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 fiancée 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 over 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.
