She's never been afraid to show off her figure, and became a household name after flaunting it in a bikini back in 2006 in the I'm A Celebrity... jungle.

And now, while in the midst of her current sunny getaway, Myleene Klass flaunted her incredibly lean curves in a sexy black swimsuit, posted on her Instagram page.

The 37-year-old stunner is in a secret location on holiday with her adorable daughters, seven-year-old Ava and Hero, four.

Tasty: Myleene Klass sipped on a cup of tea while showing off her incredibly slim figure in a black cut-out swimsuit while on her latest holiday

But on Tuesday it was all about her as she posted the snap on her Instagram page.

In the image, her slim shape was the centre of attention, her ample bust hoiked up in a cut-out black swimming costume that almost looked like a bikini.

Featuring a revealing cut-out panel and straps over her slender hips, the former Hear'Say star displayed her frame while sipping on a cup of tea, her locks slicked back after presumably taking a dip in the pool.

Along with the image, she joked: 'Obligatory Cuppa. #britabroad.'

'Tan lines on fleek!' The 37-year-old shared another sexy snap, joking about the tan marks she will no doubt gain thanks to the cut-out style of the swimsuit

But it's fair to say that her fans were less interested in the little white mug of brew than her knockout figure.

Another photo posted shortly afterwards showed her literally leaping out of the bright blue pool, a slick of glamorous red on her lips as she beamed with joy.

She wrote alongside the equally-alluring photo: ;Tan lines on fleek #littlewoods #swimsuit.'

Myleene's figure has long been something that she has strived hard for: she has admitted to being overweight and her struggles over staying slim.

In a previous interview, the star - who was a size 14 when rising to fame on Popstars back in 2001 - she confessed: 'People look at me and think I'm a perfect size 8, but I'm not naturally slim.'

'I've got a mixed heritage and have hips and boobs - I'm always going to be a big girl trapped in a small girl's body!' she told Closer magazine.

And recently, after working on new TV show BBQ Champ - which saw her eating plenty of tasty treats from cooks hoping to bag a huge cash prize - she revealed she gained half a stone.

'I ate like a demon. I put half a stone on!' she said, adding that she 'didn't stop eating'.

However, it appears any extra weight she may have put on has long gone, as she showed off her incredibly svelte figure in her new snaps.

The multi-talented star loves nothing more than getting away from it all, and is spending time with her little ones in an exotic location, one she has not yet disclosed with her fans.

On Monday, taking to Instagram once again, Myleene shared a sequence of intimate snaps posing with Ava and Hero, the girls dressed up as mermaids and splashing their long fishtails by the pool.

The Classic FM presenter showed off her goofy side as she frolicked in the water with her girls enjoying some quality time together.

She may be on holiday, but it's clear to see Myleene wasn't off duty when it came to her poolside style.

The singer oozed glam by tucking her brunette locks under a cream hat.

The multi-tasking mum looked incredible in the white bandeau bra and matching briefs set, which had an intricate gold detail on it adding a touch of class.

So cute! Myleene held youngest daughter Hero up in the air and captioned the moment on Instagram: 'My water baby'

As she showed off her super-svelte figure in her sexy swimwear it bared a resemblance to the white bikini that rejuvenated her career on I'm A Celebrity... Get Me Out Of Here! in 2006.

Myleene has enjoyed a string of holidays of late - jet-setting between various exotic locations for work and play.

She recently returned from Canada for a work trip this month and posted a passport selfie on Instagram.

In August the bronzed goddess jetted out to Ibiza to enjoy some relaxing family time as she posted photos with her daughters on a chartered luxury boat.

In July she flew to another undisclosed exotic location and kept her Instagram followers updated with daily bikini pictures from her family holiday.
