The 37-year-old singer and his wife, Luisana Lopilato, have welcomed son Noah into the world after the 26-year-old beauty gave birth in the early hours of yesterday morning in Vancouver, Canada.
The It's a Beautiful Day hitmaker wasted no time announcing the news, taking to Instagram to post a picture of the happy couple and their newborn baby in hospital.
He wrote, "Overjoyed and filled with gratitude at the arrival of our son."
Michael previously said the day he found out he was going to be a father was the "greatest day" of his life, and the couple discovered in March they were expecting a boy.
Earlier this month, the crooner revealed he was sticking close to Luisana ? who’s Argentinean ? just in case she went into labour.
He said, "I'm about 15 to 20 minutes away from home. Just in case anything happens, I'm there.
"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."
