They have been enjoying the sights of Buenos Aires.
And Michael Buble and his 28-year-old wife Luisana kept it casual as they went for a meal at the Happening restaurant in the city on Wednesday.
The Canadian singer was dressed in a denim and leather jacket, teamed with a pair of black jeans.
Meanwhile his wife wore her hair down in loose curls and covered up her burgeoning bump with a silk mint green top.
She also wore a pale turquoise necklace and leather jacket.
The blonde finished her look with a pair of washed out blue jeans featuring rips at the knee and boots.
Michael protectively held his wife's hand as they left keeping a close eye on her.
Luisana is expecting her second child with the singer.
The pair already have a two-year-old son, Noah.
They were accompanied by Luisana's sister Daniela Lopilato, for their dinner date, who could be seen walking out behind the pair.
