As a former Victoria’s Secret model, keeping in shape is a prerequisite of the job.

But mother-of-two Doutzen Kroes showed she is very serious when it comes to staying fit as she hit the beach this week.

The Dutch beauty, 30, is in Ibiza enjoying a romantic getaway with husband DJ Sunnery James, who is working on the party island’s summer club scene.

And while they stole a few hours together on the beach, all eyes were on the supermodel as she hit the surf.

The two-piece showcased the work which had gone into her gym sessions, and Doutzen had clearly been focusing on her crunches, as she boasted a very impressive six pack.

With her hair up in a simple knot, she enjoyed a splash in the ocean before strolling along the sand with Sunnery, the father of her two children, Phyllon and Myllena Mae.

The pair stopped off for a selfie together as they lapped up the Mediterranean sun.

Of course, being married to one of the world’s most beautiful women, Sunnery also took several snaps of his stunning wife as she strutted her stuff along the shore.

It’s only a year since the model welcomed her daughter.

In an interview previously, Kroes revealed she maintains her stunning figure through a combination of diet and exercise.

‘I take really good care of my body,’ she said. ‘I try to sleep as much as I can, and I go to the gym a lot because my body enjoys a good work out.

‘I keep my skin hydrated, and I avoid eating too many sweets or too much chocolate. In any job, you have to give up certain things, and I believe that having a good quality of life means enjoying certain things only in moderation.

‘I love my job, and so I could never complain about making these sacrifices.
