Michael Bublé has announced the news of a new arrival to their family on social media, and revealed the baby name they picked.
The proud daddy chose to share the news of the birth of his second son on his Instagram account, with a sweet photo of him, his wife and of course their brand new family member.
'And then there were 4. Introducing Noah's little brother Elias Buble #family #blessed #brothers', he captioned the photo on Twitter and Instagram.
The Grammy winner and his wife Luisana, who's an Argentinian actress, revealed they've chosen the name Elias for their newborn son.
The couple announced they were expecting a baby last July, via their eldest son Noah with a cute little Instagram video.
In it, Noah is asked by his dad 'who's that in there?', referring to Luisana's baby bump, to which he excitedly replies: 'Baby!'
The couple have since shared several updates of the 28-year-old's pregnancy, including her first sonogram and her beautiful growing baby bump.
The couple tied the knot nearly five years ago, in April 2011, in a ceremony in Buenos Aires attended by 300 family members and friends, as tradition dictates in Argentina, where Luisana is from.
Michael has previously discussed his experience with fatherhood, saying that his fatherly instincts didn't kick in instantaneously after Noah was born.
'I didn't have that overwhelming feeling of love. I'm being honest with you', he said on a Canadian talk show, The Social.
'That next night (after the baby was born), it really clicked. I was looking at him and all of a sudden, I got it... I sing to him all day and all night. When he's crying with somebody else and I hold him and I sing to him, he just stops. It's really cool.'
He's also made it clear that he wanted another child. In an interview with a Dubai-based magazine, the Canadian artist said: 'But it's the best, I can't wait to have to another, and he makes me better at everything.
'He is what I live for and he puts everything into perspective. I say it all the time: this is my job, and really it doesn't define who I am. I am a poppa and a husband.'
Congratulations on your gorgeous new addition!
