The 'Keeping Up With The Kardashians' star is thrilled to be expecting his first child, a baby girl, with his fiancé Blac Chyna and his mother Kris Jenner is pleased to see him "engaged in life again".

She said: "It's wild. it's been very exciting to see Rob on this journey. It really has ... You know, he was in a place where he wasn't feeling good about himself, and he didn't really wanna get out and about, so this has really been life-changing for him, and obviously, as his mama, it's been ... I'm just happy he's engaged in life again ...

"I think he's in a relationship and he's feeling loved and he's expecting a baby and he's got this new family unit that he's a part of now, and I think every single thing that's happened to him over the last year has been very significant in helping him overcome some of his challenges and adversities he's gone through lately. But I think he's in such a good place."

And the 60-year-old matriarch is feeling positive that her 29-year-old son will overcome his weight troubles as he has always been "so athletic".

She added to E! News: "Any time you get down on yourself, it's always a process to get back on top of it. And Rob has always been so athletic, he was the star track guy in high school and a basketball player, and he was the runner up after 20-whatever weeks on Dancing With the Stars, and dancing live in front of 40 million people or whatever it was ...

"He's been such an amazing athlete and in such great shape and very athletic his whole life, so this is not in his comfort zone. This isn't something he's experienced, so it's hard. It's hard for him to get the weight off like it is for any of us, so he's definitely been challenged by this. He'll work through it. I really have faith in him. He's just gotta put his mind to it."
