Kourtney Kardashian shows her body confidence in a daring low cut swimsuit

She's worked hard to get her body back into swimsuit shape.
And Kourtney Kardashian was nothing short of jaw-dropping on Sunday as hit the pool in Miami wearing a daringly low cut black one-piece.

The 34-year-old reality star indulged in some poolside fun with her husband Scott Disick and their two children, Mason and Penelope.

Looking sleek for a family pool day! Kourtney Kardashian was nothing short of stunning in her sexy low-cut one piece on Sunday as she enjoyed a poolside frolick with husband Scott Disick and their children Mason and Penelope

In your face, Scott! Kourtney was full of smiles as she leaned over towards her husband giving him a full view of her smashing bikini body

Kourtney's flattering swimsuit boasted a low back and even lower ront, revealing as much as possible without being inappropriate.

Scott's eyes were glued to his girlfriend as she splashed about in the pool with their son Mason.

The mother-of-two was clearly not afraid to ruin her hairdo, which she proved as she stepped out of the pool with wet tresses.

Ready for a dip! The Keeping Up With The Kardashians star sported a casual ponytail before she dunked her head under the water

Penelope's turn! Kourtney and Scott's 23-month-old daughter joined them in the pool, already looking like an incarnation of her mother and aunts as someone decided to dress her in a leopard print bikini

Mmmm, that tastes good: Penelope sucked on her mother's finger as they cooled off in the water

Happy babe: The tiny tot appeared quite content as she put her hand in the water while being held by her famous mother

The Keeping Up With The Kardashians star later lay down and caught some sunny Miami rays with Scott.

'Poolside with my dude,' Kourtney tweeted as she uploaded a cute snap of the couple snuggling up on a poolside couch.
On Friday night Scott was the guest of honour at the Bamboo Club.

Bye bye, hairdo! The curvaceous stunner dunked her hair under the water to keep cool in the Miami heat

A bundle of energy: Mason looked to be having the time of his life splashing about with his mother

The reality star mingled with other VIPs including rapper Fat Joe as he enjoyed a boys night without Kourtney.
As the host of the Friday night party Scott was also given the dubious honour of being a judge in the Brazilian bikini competition.
And ladies flocked to to try to secure the title of Miss BumBum by flashing their derrieres in skimpy bikinis.

'Poolside with my dude': Kourtney took time away from the water to lounge around with Scott, who seemed decidedly content to have his stunning wife by his side

However, despite the big night, on Sunday Scott only had eyes for one lady in swimwear - Kourtney.
It seems things are going well for the pair, who have had their fair share of relationship troubles - all chronicled by their show Keeping Up With The Kardashians.
The relaxing afternoon was surely welcomed by Scott, who looked hilariously disinterested by the couple's shopping expedition earlier in the day.

The famous couple headed out to Bal Harbor, where they spent some time emptying their wallets.

Frighteningly low! The 34-year-old reality star's swimsuit threatened to pop off if she made any sudden movements... luckily, she kept it under control

Had enough? The mother and son played around for a while before climbing out to relax with Scott and Penelope  

Water baby! Whereas plenty of celebs tend to steer clear of anything that ruins their hair and make-up, Kourtney seemed to be loving the cool water

Kourtney, who obviously loves a spot of shopping, had her eyes darting left right and centre at the famous shopping spot, whilst Scott appeared somewhat less enthused.

Kourtney rocked a stunning beach-chic look for the shopping expedition, donning a soft draping blue and green onesie over casual flip-flops.
The star's Ray Bans shielded her eyes and her tresses were pulled back into a casual ponytail as she looked nothing short of chic.

Sitting pretty: Kourtney later accessorised her swimming costume with a hat as she perched on a sunlounger

Accessory queen: Among the jewels Kourtney sported was a jade ring and a gold bracelet

Scott was also doing well in the fashion stakes with his black and white striped T-shirt and baby blue shorts - but he had a minor fail in the shoe department.

The 30-year-old wore a rather gaudy pair of leopard-print loafers, which looked more like bedside slippers than anything you'd wear in public.

Doing what she does best: earlier in the day on Sunday, Kourtney and Scott spent time at a popular shopping spot in Bal Harbour for a little retail therapy

Sussing out her surroundings: the reality star looked perfectly content surrounded by luxury boutiques galore

Kourtney appeared to be happily chatting with shop assistants, before coming outside to find her husband looking decidedly over it.

And it looks like the happy mother wasn't shopping for herself on this particular occasion.

She carried a bag from Bonpoint, a famous boutique specializing in luxurious clothing for children and babies, having perhaps picked up some goodies for Mason or Penelope... or perhaps for her sister Kim's newborn baby North.

Bored, Scott? As Kourtney seemed to be looking around for her next shopping target, her husband seemed to be dreaming of a way out of there

Found something! The brunette bombshell emerged from children and baby wear boutique Bonpoint carrying some goodies, perhaps for her little ones or even for her sister Kim's baby North

Great outfits... except those shoes! Kourtney looked stunning in a blue and green beachy onesie, whilst Scott had a minor fashion slip-up with those leopard print loafers
