Michael Buble's priorities have changed with his wife getting pregnant.

The 37-year-old singer's wife Luisana Lopilato is pregnant with the couple's first a child - a boy, due in July - and the star revealed he isn't worrying about whether his new album 'To Be Loved' sells well enough to continue his success.

He told the Sunday Telegraph newspaper's Seven magazine: ''Do you know what's weird? That's not happening, that insecurity. Everything has changed. It's all changed because of the baby.

''I'm having a difficult time doing these interviews. I'm proud of this record, it's a beautiful record, possibly my best record. It's different and I was brave but being brave stemmed from not caring. That sounds cold but I've got bigger fish to fry.''

Whereas the 'Haven't Met You Yet' crooner knows the importance of touring to support his music, he also knows ticket and album sales aren't all there is to life, with marriage and parenthood replacing them as his focus.

He said: ''When my manager says, 'I wonder if we're going to sell two million or eight million', I'm thinking, 'Yeah, either is a great bonus, but let's hope my wife is healthy and my kid is healthy'.

''I'm 37 years old and I'm starting to think, what's it all about? It surely isn't about how many records I can sell or how many stadiums I can fill.

''My perspective has definitely changed. I have no drama to tell you about. I wish I could say these songs came from misery or heartbreak.''
