Michael Buble says he is ''penis perfect'' despite bad looks.

The 'Haven't Met You Yet' hunk - whose wife Luisana Lopilato is pregnant with their first son - joked while he doesn't have a great face or body, his best asset stays hidden.

He told The Sun newspaper: ''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.

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

The crooner has previously admitted he was an ''a**hole'' in the past, and revealed he was ''insecure'', lacking the confidence he seems to have now.

He said: ''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.''
