Michael Bublé and wife Luisana Lopilato confirm they're expecting their third child together

Michael Bublé and wife Luisana Lopilato have confirmed they're expecting their third child together.

The lovely baby news were confirmed by the couple's rep, who told E! News that the singer and his wife will indeed welcome another baby into their brood.

The confirmation comes after rumours started in Argentinian press, Luisana's native country, fuelled by a picture the mum posted, where she's seen wearing a loose-fitting top.

Despite confirming the pregnancy, the couple didn't reveal when their bundle of joy is due to be born, or if they know the gender of their third child.

Michael and Luisana's exciting news comes after a tough time for the family, as their eldest son, Noah, was diagnosed with liver cancer in November 2016.

Noah, who's now four-years-old, has since undergone treatment and ahead of celebrating Christmas as a family, Michael said his son was doing 'very well'.

'[He's] doing very well,' the Canadian star told Entertainment Tonight in December. 'He's an energetic little boy! Events like this put everything in perspective. There's no doubt Christmas will be extra special at the Bublé household this year.'

The pair, who are also parents to two-year-old Elias, have taken a break from their careers since their son's diagnosis, in order to be there for him.

Michael's professional hiatus saw him pull out from presenting the BRIT Awards last year, in what would have been his first time as a presenter at the awards ceremony.

Luisana also opened up about Noah's cancer battle in June, explaining on Argentinian TV how the family coped with this difficult time.

'We did all the tests, and finally, we found out that it was what it was. These things, when they happen to you in life, they make you realize that the most important thing isn't what you thought it was — it's to have faith, to be strong.

There were nights I couldn't sleep, that I prayed to God. Because it is a long process — but thank God the worst is over.

'We had to stay positive and leave it in God's hands. There wasn't a single week where I didn't go to church. Every night I prayed for strength to go on', she said.

The couple have been together since 2011, having tied the knot only a few months after first meeting. They welcomed their first son in August 2013, and their second baby boy followed in January 2016.
