Michael Bublé believes fatherhood gave him ''context''.

The 41-year-old singer songwriter - who underwent surgery on his vocal cords in June this year - has admitted he feared the worst for his music career prior to the operation, but being a father gave him more purpose to his life than he had gained ''anywhere else''.

Speaking about fatherhood to The Sun newspaper, Michael - who has sons Noah, three, and eight-month-old Elias with his wife Luisana Lopilato - said: ''Being a dad gave me something that I couldn't have got anywhere else and it gave me context. So I thought, at the worst, at least I had a great run and I've loved what I do.''

And the 'Home' hitmaker has revealed he wanted to ''take great control'' of his career by producing his own music.

He said: ''For the first time in my life, I decided I would take great control by producing my record.''

The Canadian singer feels he has gained more ''perspective'' since becoming a parent, and has realised his work is just a job and doesn't ''define'' him.

Speaking previously, he said: ''I think being a dad gives you perspective. I think really being a parent is a massive blessing.

''It's allowed me to understand deeply that what I do for a living - creating music and art and getting to be a part of a fragrance or a movie - is my job. It isn't what defines me. What defines me is I'm Noah and Eli's dad.''

Michael is thankful for his family as they help him overcome his worries and fears.

He said: ''When I'm nervous and I'm insecure and I'm scared of challenging myself or leaving my comfort zone, [fatherhood] just gives me context and allows me to understand what's important.''
