The ballad, which John wrote about his wife Chrissy Teigen, was a global smash hit and he isn't bothered about trying to recreate that with another song because he believes it would be impossible.

He told The Courier Mail: "I didn't ever try to pressure myself to match the commercial success of 'All Of Me'; it can't get much bigger than that song and you should be grateful for that success."

However, John also revealed that he has been getting inspiration for his new songs from his baby daughter Luna.

He explained: "I had songs going around in my head about my daughter before I even met her. There are a bunch of other songs about Luna that didn't make the album because I like to keep going until I find the right song."

Meanwhile, John recently admitted he doesn't think he would have landed a record deal if it wasn't for Kanye West.

The 37-year-old singer is forever "grateful" that the 'Famous' rapper took interest in his music and signed him to his record label GOOD Music as he doesn't think he would have inked a major deal without his mentoring.

He said: "I don't know if I would've gotten signed to Columbia and Sony without [Kanye's] help and his work with me on my music back then, so I'll always be grateful to him for that.

"I got turned down by every major record label who I met with - including Sony [Legend's current record label] - and you know, I had to keep persisting despite getting told no and wait till I got to yes."

However, Legend - who released his debut album 'Get Lifted' in 2004 - admitted he thinks it was "helpful" he became famous when he had matured into an adult because he was already aware of the "real world".

He explained: "I think it was helpful for me to become famous when I was an adult already; I was twenty-six years old. I think it's harder for people that become famous when they're a lot younger because you never had to be an adult without being in this very unrealistic world. It is unrealistic if you don't know what the real world is like and me having lived in the real world for a while was very helpful."
