The 'All of Me' hitmaker admits he is worried for his friend after the rapper was admitted to a Los Angeles hospital suffering from "exhaustion" and "sleep deprivation".

John told CBS This Morning: "We were with Kim [Kardashian West; Kanye's wife] actually, you know, right before all of that. I was concerned by what I saw, so hopefully he's getting some rest and some time to figure things out."

And the 37-year-old singer hopes Kanye, 39, will get the rest he needs.

Speaking to Entertainment Tonight, he added: "I'm not gonna speak out of term and speak for him. All I can see is what [Kanye] said to the public - and that is he's tired and needs some rest.

"I think he's been through a lot lately with what happened to Kim. I think if he needs to rest, I think his fans will be patient and let him rest. He'll come back stronger, hopefully ... He's the one that signed me, he's the one that helped discover me and help me get a record deal. I wouldn't be where I am now without him. I am very grateful to him."

Meanwhile, it was previously claimed that the father-of-two - who has three-year-old daughter North and 23-month-old son Saint with Kim - feels he is "under spiritual attack".

A source said: "He feels like he's under spiritual attack, and has been for a while. It's not just the big things; it's smaller, quieter things, internal things. You might think that it's about Kim's robbery, and while that didn't help, that's not what's going on here. He's dealing with a lot more subtle issues.

"Sometimes, darkness creeps in, and Kanye wrestles against it. He talks about that a lot. It's exhausting, and it takes everything he's got. He's just so tired now; he's very low energy and feels like there's a grieving in his spirit. It's very hard to explain, but something has happened recently, where he's not the Ye that everyone knows ... He's in a very reflective place right now."
