Michael Buble ready for fatherhood

Michael Buble is keen to start a family with model wife Luisana Lopilato - because he's "jealous" of all his friends who are fathers.

The couple exchanged vows in Buenos Aires, Argentina in March (11) and Buble is eager to welcome a child - when his model partner is ready.

He tells ET Canada, "I've said to her (Lopilato) a million times I'd love to have kids. But I always say to her, 'When you're ready - when you feel like you've lived and you've partied and done all the things you want to do. When you've worked your butt off, then tell me.'

"All my friends have babies so every time one of them says, 'Guess what, you're going to be an uncle,' part of me is so happy for them and the other part of me is jealous."
