Model Doutzen Kroes shows off her perfect abs

Victoria's Secret model Doutzen Kroes shows off her perfect abs as she plays in the Miami surf with husband Sunnery James

With such a toned tummy it's hard to believe that she's also a mother.

And Doutzen Kroes proudly put her enviable figure on display as she and husband Sunnery James played together in the waves off South Beach in Miami on Sunday.

Rocking out: Doutzen Kroes showed off her flat abs in a flesh-baring bikini as she splashed in the waves with her husband Sunnery James in Miami on Sunday

The 28-year-old, who is mother to her two-year-old son Phyllon, highlighted her famous assets in a jewelled pink triangle top bikini and matching barely-there bottoms.

The Victoria's Secret model giggled as she splashed around in the bright blue Atlantic Ocean, holding tight to her DJ husband as the waves crashed around them.

They even managed to sneak in a quick game of leap frog, with Doutzen wrapping her arms tightly around her husband in the shallow water.

The couple have been married for three years, and despite both having successful careers that take them all over the world, they always manage to make time for each other.

The Dutch supermodel couldn't keep from mixing in a bit of work on her outing, posing for some silly shots as a friend snapped away.

She showed off her best moves, including a few in-your-face snaps with her posterior perked up for the camera.

Doutzen has no troubles putting her rock-hard body on display as she has been a Victoria's Secret Angel for over six years.

And she recently revealed that the key to maintaining her slim figure is by carefully regulating what she eats.

'I always eat in moderation,' she told Fit Sugar last year. 'If I order French fries I have a salad and I share [the fries] with my friends.

'I don't tell myself to not eat anything to stay away from all sugar or all fries or all the good fried foods. But I eat it in moderation.'

On Saturday night the trio packed in the crowds at the LIV night club in Miami.
