Khloe Kardashian reveals her new found body confidence as she strips off during a photo shoot in St Barts Khloe Kardashian/Twitter

Khloe Kardashian has taken a leaf out of big sis Kim Kardashian West's book, by baring her bottom on the internet. While Kim famously threatened to "break the internet" with her posterior revealing shot on the cover of Paper magazine, Khloe spontaneously stripped off while on holiday in St Barts.

The 31-year-old posted the nude photo on her website KhloeWithAK.com on 18 December. She wrote: "Soooooo yeah this happened...." explaining that it was the result of a combination of dutch courage and boredom.

The photos were reportedly taken by her 20-year-old sister Kendall Jenner after the pair got "bored" after "everyone else had gone to sleep". Khloe was also assisted on the impromptu shoot by Joyce Bonelli, Jen Atkin, and Jen's husband, photographer Mike Rosenthal at Atkin's bungalow.

Describing how the evening unfolded Khloe said: "We started drinking a little and somehow this impromptu photo shoot turned into a fully nude photo shoot. Even though I've worked really hard on my mind and body to get to this point, I am still shocked I had the courage to do this shoot," she admitted.

She confessed that she may have had "a little too much liquid courage." Shed added: "And I'm not getting any younger so it's now or never."

But, the Keeping Up with the Kardashians star, who has been working out diligently to achieve her toned and slender figure, said she had no regrets about sharing the image, commenting that she is "so f***ing happy" she did it.

"These pictures are to die for! I cannot believe how unbelievably gorgeous they are!" she said. Describing the shoot as one of her "favorites to date", she gushed: "Thank God I have incredibly talented best friends or we could never capture moments like this."

It's a sea-change for the reality TV star who previously described her nerves at stripping off for animal rights campaigners PETA and for her Complex cover in July.

Following her split from husband Lamar Odom, Khloe has undergone something of a transformation, following a strict gym regimen. The secret behind her new found body confidence is documented in her bestselling book, Strong Looks Better Naked.

According to Deadline she is also due to star in a new show with E!, Revenge Body, which chronicles peoples transformations from "frumpy to fabulous".
