Cute baby Noah arrives to proud dad Michael Buble and wife Luisana

Luisana, 26, gave birth to her son Noah at a hospital in Vancouver, and Michael just couldn't wait to share the news with his fans.

Posting an image on his Instagram page which showed his wife clutching their baby boy, while he grinnd behind them wearing hospital scrubs, Michael wrote: "Overjoyed and filled with gratitude at the arrival of our son Noah Bublè. Born this morning, August 27th at 2:26 am in Vancouver, Canada."

The 'It's A Beautiful Day' singer is pictured beaming from ear to ear still wearing a hair net as his wife smiles for the camera and cradles little Noah.

Luisana looks radiant in the picture which appears to have been taken just moments after she gave birth at 2.26am in a hospital in Vancouver.

The Argentine actress and model had revealed that she and her husband of two years were expecting in January when she uploaded a video message to fans on her website.

Overjoyed and filled with gratitude at the arrival of our son Noah Bublè. Born this morning, August 27th at 2:26 am in Vancouver, Canada.

She also released a scan picture of the unborn child and photograph of the expectant parents kissing, with the message: "We're having a baby Buble!" Buble, meanwhile, could barely contain his excitement over his impending fat

herhood.

During an interview he said finding out his wife was pregnant "was the greatest day of my life".

In March when the couple discovered they would welcome a son Buble tweeted: "We have just come from the hospital and the sonogram was pretty clear — it's a boy! We are thrilled."

More recently, the singer admitted that he was terrifed of accidentally missing the birth and was therefore staying close by to his wife in the final stages of her pregnancy.

"I'm about 15 to 20 minutes away from home. Just in case anything happens, I'm there," Michael explained.

"It's scary for her. She's in a country that's not her country, people are speaking a language that's not her first language.

"So, you know, I've got her whole family here so there's a good support system."

Michael began dating Luisana in 2008, shortly after ending his three-year relationship with British actress Emily Blunt. The pair became engaged in November 2009, and married in March 2011 in Buenos Aires.
