Michael Buble is set to tie the knot on 2 April

Michael Buble was previously engaged to actress Emily Blunt

Canadian crooner Michael Bubl� will break a thousand hearts when he marries his Argentinian fianc�e Luisana Lopilato this weekend.

Michael met actress and model Luisana, 23, when she starred in his music video for Haven't Met You Yet and proposed to her in November 2009.

The couple will become husband and wife in a South American wedding on Saturday 2 April and then plan to celebrate again in Canada with the Bubl� clan.

?We have one in Argentina for her family and a few of my family,' says Michael, 35.

?And then I have a thing called an unwedding a month later in Vancouver.

?It's not a wedding, it's like a big party.'

Groom-to-be Michael insists he isn't worried about his big day, as long as his bride has a good time.

?I'm not nervous at all,' Michael reveals on Live! with Regis & Kelly.

?I just want it to be good for her.

?For me, it's one of those things where I say, "Just tell me what to do", it doesn't matter what it costs, let's make it right.'
