Michael Buble and his wife Luisana Lopilato have welcomed a baby daughter.

The Argentine actress posted a black and white photo of the newborn’s hand on Instagram.

She wrote in Spanish: “How to explain that our heart explodes with love? That there’s not enough hours in a day to think about it.

“I thank God for making us this gift of life and happiness! Because looking in her eyes is looking at heaven itself!”

“We love you to infinity and beyond. We waited for you not only to grow as a family… you gave us light, hope, you are and will be our souls’ life.”

The couple are already parents to Noah, five – who has been battling stomach cancer – and another son, Elias, who was born in January 2016.

They announced Noah’s diagnosis in November 2016, when he was three.

At the time Buble said they were “devastated” and were suspending work commitments to devote all their time to looking after him.

In April this year, Lopilato said the couple remained hopeful and were “looking forward to thinking about the future” and seeing their children grow.

During a recent show in London’s Hyde Park, the Canadian jazz singer brought the little boy out on stage after telling the crowd there were “many moments” he thought he “might not come back” to showbiz.
