Michael Buble can't wait to be a ''hands-on dad.''

The 37-year-old singer's wife Luisana Lopilato is due to give birth to their first son later this year and Michael is planning to rearrange his work commitments so he can be there for his child as much as possible.

Michael said: ''I've changed my touring schedule so it's no longer a month and a half and then a week off. Now it's three weeks on and two weeks off. I can't wait to be a hands-on dad when the baby arrives.''

The Canadian singer has already vowed to do his fair share of the less-than-pleasant aspects of parenthood, despite being originally unsure if he was ready for children.

He vowed to Closer magazine: ''I'll be doing the late nights and changing the nappies.''

Michael - who married Argentinean model Luisana a year ago - says his wife's pregnancy has brought them closer than ever, but he admits to ''driving her crazy'' with affection.

He said: ''When I found out Luisana was pregnant, I was so in love with her that I was driving her crazy. I just wanted to kiss her and was touching her stomach going: 'I love you so much! I really love you.' ''
