The reclusive reality TV star has embraced the spotlight since he started dating Blac Chyna and Scott is delighted that Rob has become more outgoing in the past few months.

He told PEOPLE: "I'm just so grateful and happy about it. There's literally nothing but happiness.

"I'm just happy that he's happy."

Recently Scott - who split from the sock designer's older sister, Kourtney Kardashian, last year after nine years together - revealed he believed Rob found being propelled into the spotlight "a lot to handle".

Speaking on the 'Kyle & Jackie O' radio show, he said: "Things are difficult sometimes, especially when you become in the spotlight very quickly overnight. Your whole life changes very quickly. He was just getting out of college, and then he became famous quickly, and I think it was a lot for him to handle.

"I don't think that was the path he wanted to be on, and he just got caught in the middle of it.

"He's one of the greatest guys I know. He's got a good heart, and he's just an amazing guy all round.

"He's doing great - he's doing actually unbelievable.

"He had to take some time off, and I think he was a little down-and-out, but he's doing a lot better, and I think he's very happy."
