He's recently slimmed down considerably thanks to a dedicated gym regime.

And it would seem Michael Buble was determined to make the most of his new-found trim physique as he stepped out in London on Tuesday.

The 37-year-old singer showed off his slim legs in a pair of skinny jeans, while proving the paunch he used to sport is most certainly a thing of the past by showcasing his flat tum in a tight-fitting V-neck T-shirt.

And the Just Haven't Met You Yet hitmaker has clearly been taking a few style tips from his stunning wife, Luisana Lopilato, with the pair heading out in matching leather jackets.

The Canadian crooner completed his daytime look with a pair of aviator-style sunglasses and a large black backpack.

With the singer usually being a fan of classic tailored suits, this ensemble seemed to mark a trendy new turn for Buble.

Meanwhile, model Luisana, 25, looked effortlessly chic in a leather trench coat with large gold buttons as the couple departed London's Soho Hotel.

And the Argentinean beauty seemed to be having a lovely time in the capital, and was grinning from ear-to-ear as the couple got into a waiting vehicle.

Michael first attracted comments about his weight when he sported a paunch while on holiday in Barbados in 2011.

But in September he revealed his new slimline physique and chiselled cheekbones as he attended a Milan Fashion Week event in Italy.

The star married Luisana in 2011 following a two-year relationship, and he has recently been seen accompanying her on a number of her regular gym sessions.

Buble is currently in London promoting his upcoming residency at the O2 in 2013.
