Michael Bublé created ''three options'' before launching his fragrance By Invitation.

The 41-year-old singer, who unveiled his debut perfume earlier this year, has admitted he had a trio of scents to select from, and although he had one favourite out of the selection he brought the product home to get the approval from his wife Lusiana Lopilato to give him ''confidence'' in the perfume.

Speaking about the cosmetic item, the 'Home' hitmaker: ''I did a lot of research. I went to the perfumers, to the laboratory.

''We created three options, one of which I loved, then we did the market research with about 3,000 different women.

''Ninety per cent of them chose what I had liked, which gave me confidence. God love me, I'm a man, so it was important to know what a woman thought. I brought it home to my wife and she really liked it and for me that was obviously really important.''

And the dark-haired powerhouse has revealed he trusts his spouse - who have sons Noah, three, and nine month old Elias together - and ''respects'' her ''great sense of style''.

He explained: ''And more than that, I have a lot of respect for her sense of style. She's got a great sense of style. She's got a great sense of personal style. It's nice for me. ''

Michael - who married Luisa in 2011 - has revealed he always seeks advice from his partner, and even consults her on his music.

He told HELLO! magazine: ''You know, even with my music, I ask her those questions - what song or what do you think about this, or which cover? There are so many questions. She's my best friend. I ask her opinion.''
