They welcomed their first child together, baby son Noah, into the world back in August.
But Michael Bublé and his model wife Luisana Lopilato proved they've certainly still got that special spark as they stepped out on a family shopping trip in Berlin, Germany, on Monday afternoon.
Accompanied by their adorable five-month-old son, the loved-up couple looked the picture of happiness as they shared a tender kiss while browsing the wares at the city's upmarket Galleries Lafayettes.
The Argentinean model and actress looked cute as a button as she grinned happily while trying on a stylish black fur hat.
Pushing her hair out of her eyes, Canadian crooner Buble couldn't resist planting a tender romantic kiss on his wife's lips as they chuckled away together.
After enjoying a brief moment alone, the couple - who tied the knot in March 2011 - were back to their parenting duties, with Luisana picking up little Noah for a cuddle as the family wandered through the store.
Luisana, 26, opted for a low-key look for her daytime outing, wrapping up against the chilly winter weather in a khaki coat with leather sleeves, which she teamed with jeans, shoe boots and a stylish plaid scarf.
Meanwhile, Michael, 38, opted for an equally casual vibe in a black padded jacket and jeans as he cemented his hands-on dad title by lugging Noah's heavy-looking pushchair about as the family and a pal wandered around Berlin.
And little Noah looked the picture of contentment for the family, and was bundled up in an adorable sheepskin jacket and gloves while being tended to by his doting parents.
Michael Buble is currently performing in Europe as part of his To Be Loved tour, which kicked off in June and is currently set to finish in August this year.
And after tying the knot with Luisana, a huge star in South America, and welcoming little Noah into the world, Michael has insisted he couldn't be happier.
He said in a recent interview: 'I’ve got a great family. I’ve got a great, happy life.
'I’ve got a woman I’m in love with. Do I really need to sit and obsess about what strangers are saying?’
