CANADIAN crooner Michael Buble's little son is set to break hearts, if these photos are anything to go by.
The singer's model wife Luisana Lopilato was snapped stepping out with the couple's cherub son Noah in Barecelona at the weekend, after a work out session.
The singer who is on a world tour, tweeted a cute picture of him holding his crying son on his tour bus just last week.
‘‘Someone don't want to leave beautiful Barcelona!!’’ he captioned it on his last night in Spain.
The proud dad beamed with pride as he showed off his 5-month-old son and flashed a wide smile.
Touring Europe with his superstar father, Noah was pictured wearing a printed football top.
Buble was taking it easy after another crowd-pleasing performance in a casual V-neck white T-shirt.
His major world tour will see him play in Madrid today, followed by dates in Norway, Lisbon and Sweden, then Canada and Australia.
He will remain on the road until August, where he will end his glittering tour in Mexico.
Along with mum Luisana Lopilato, the trio will spend most of the globe-trotting tour together.
The busy dad picked up a Grammy Award for the best traditional pop vocal album for his music on "To Be Loved’’ last week.
The couple welcomed baby Noah into the world in Canada last summer.
The highly-anticipated birth was announced on Twitter with a private snap from the delivery room to his 1.85 million followers.
