His former WHAM! bandmates gave a beautiful introduction to a musical tribute from Coldplay's Chris Martin.
The couple shared a picture of their new bundle of joy over the weekend.
Michael Bublé and his wife Lusiana Lopilato have welcomed another little boy to their family.
Elias Bublé was born on Friday night and the doting parents took to Instagram to share the news with fans.
"And then there were 4," Bublé wrote alongside the picture of him and Lusiana holding their newborn. "Introducing Noah's little brother Elias Bublé".
This means their first-born Noah has become a big brother at two years old.
Bublé met his Argentinian wife in 2008 and she appeared in his music video for 'Haven't Met You Yet'. The couple got engaged in 2009 and tied the knot in Buenos Aires in 2011.
They welcomed Noah in August 2013 and now they have another addition to their family!
