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. 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.
