Cheeky singer Michael Bublé has revealed his "perfect" asset in a new interview.

The Canadian crooner is modest about his hunky good looks, but thinks he has one saving grace.

The star - whose stunning wife Luisana Lopilato is pregnant with their first child - quipped that his asset is well hidden though.

In an interview with British newspaper The Sun: ''I've got big ears, a really weird nose, a couple of chins, I've never had abs, I've got legs like a chicken.

He added: ''But that part's really good. It's not picture perfect, it's penis perfect.''

Bublé has previously admitted he lacked self confidence.

He explained: "When life is good you should just really appreciate that. I used to be a professional a***hole. A lot of that came from insecurity and not being able to live in the moment.

''When my last relationship ended I had to ask myself a whole bunch of questions.

''The difference is some people will know it and want to change, others won't, but I thought if I don't I'll probably end up alone with long fingernails. I was pretty insecure.''
