The 42-year-old singer has confirmed that him and his spouse Luisana Lopilato - who are already parents to sons Noah, four, and Elias, two - are set to welcome their daughter into the world in just three weeks' time following months of speculation.

Speaking on Ireland's 'Today FM', the 'Haven't Met You Yet' hitmaker said: "I've got my first little girl coming in three weeks, and I've actually never said that before in public. I've got a daughter coming."

Michael announced that him and the brunette beauty were pregnant again when he hosted the Juno Awards in Vancouver, Canada, back in March.

He joked: "Oops, you did it again -- my wife and I are pregnant with our number three. I love you so much, mi amor."

However, rumours that they were expecting again began to swirl a few weeks prior to that and Luisana's actor brother Dario made the situation worse when he stumbled over his words when he was asked about the speculation surrounding his family.

He said: "I wouldn't be able to tell you ... I swear the truth is I couldn't tell because I don't, I don't, I don't know. When it comes to thinking about [names], I prefer it to be something specific because you begin to get excited. So I really couldn't tell you."

The couple's eldest son Noah was diagnosed with cancer in 2016 but Michael has revealed that the child is "progressing well" following his successful treatment.

Speaking previously, the Canadian singer said: "We are so grateful to report that our son Noah has been progressing well during his treatment and the doctors are very optimistic about the future for our little boy.

"He has been brave throughout and we continue to be inspired by his courage. We thank God for the strength he has given all of us."
