Michael Buble and wife Luisana Lopilato became new parents on Tuesday.
The 37-year-old Grammy Award winner announced the news by posting a photo on Instagram.
"Overjoyed and filled with gratitude at the arrival of our son Noah Bublè," he captioned the photo of his newborn baby with Lopilato. "Born this morning, August 27th at 2:26 am in Vancouver, Canada"
According to US Weekly, Buble canceled his "Today" show appearance earlier this month, as he anticipated the baby's birth.
Buble and Lopilato first announced the pregnancy back in January though a sonogram posted on Lopilato's YouTube account. The 20-second video ends up with words: "We're having a baby Buble!!!!"
The Canadian singer and his Argentine actress-wife got married in 2011, after meeting in 2009 during a concert in South America.
