The 41-year-old singer told fans on social media in May (16) that he was going to have to take some time off "due to pending vocal surgery which will require a period of time for me to rest and recover".

"No talking or singing for a while but my doctors expect a complete recovery," he added in his message.

Father-of-two Michael has now revealed that while the operation was successful, prior to going under the knife he felt more than a little anxious about what would have happened if it had gone wrong.

“Being a dad gave me something that I couldn’t have got anywhere else and it gave me context," he said during an interview on U.K. television show Lorraine on Thursday (13Oct16). "So I thought, at the worst, at least I had a great run and I’ve loved what I do."

Michael has been doing the rounds to promote his upcoming album Nobody but Me. And during another interview with Hello! Canada, the singer admitted his sons, three-year-old Noah and eight-month-old Elias, have given him a renewed motivation when it comes to his personal and professional lives.

"That’s all that’s important - your kids," he told the outlet. "That’s what defines me. I’m a dad first and then all this other stuff is a really great icing on what is the cake of life. So I think that you just have to hope that the people around you love you, and that your kids give you a part of that purpose, and you somehow balance it out with being given purpose in your own job, in your work and all of that stuff."

Michael is married to 29-year-old Argentinian model and actress Luisana Lopilato.
