Now Kourtney Kardashian reveals a little too much derrière as she slips on another low-cutting swimsuit while bathing in pool

She made a remarkable transformation after shedding over 40 pounds following the birth of her one-year-old daughter Penelope.
And Kourtney Kardashian is clearly enjoying a renewed confidence in her body as she has taken to wearing ever more revealing swimsuits.
Over her week-long stay in Miami, Florida, the 34-year-old has been spotted parading around in various skimpy bikinis - and her most recent pool session on Monday was no different.

Sporting a cutaway one piece, the doting mother-of-two offered a little more than she bargained for as she waded into the aqua-blue water.

The reality star's swimwear ran a little too low, offering a slight glimpse of the upper portions of her derrière as she joined her family in the pool.

But the mild wardrobe malfunction was made up for with the ornate pattern and well-cut design of her flattering one-piece.

Although, just the day before Kourtney was seen nearly falling out of her skimpy swimsuit, on Sunday.

Despite these near misses, the reality star is surely more focused on the intimate family time she has been enjoying with her beau Scott Disick and their two children, Mason and Penelope.

The doting parents took turns wading around in the water, alternating between their two adorable youngsters.

But, as the stronger of the two, Scott took to swimming with three-year-old Mason as his long-time girlfriend frolicked with little Penelope.

The 30-year-old father sported horn-rimmed sunglasses as Kourtney opted for some chunky Jackie O shades.

Meanwhile, speaking in an interview with US Weekly magazine earlier this year, Kourtney revealed her struggle to lose her baby weight: 'It was harder to lose weight the second time around.

'I gained 45 pounds with Penelope. I'm 5ft tall so that's a lot.

'It took me twice as long as last time but I feel healthy and really much better about it.'

Adding: 'This time, the focus is really on being a mom and being present, knowing my priorities.'
