'Finally turned into Kim!' Kourtney Kardashian fuels butt implant speculation with peachy bikini snap

Despite being at her slimmest, there's suddenly a lot more junk in that trunkKim Kardashian is undoubtedly the queen of the Kardashian bootay.

But she had better watch out because there’s a pretender to her throne in the former of big sister Kourtney , who suddenly seems to be packing a lot more junk in her trunk.

Despite being at her all time slimmest, the diet and exercise clearly hasn’t affected her bum, with the mother-of-three showing off her peachy rump on holiday with her pals.

Armed with a glass of wine and wearing a brazillian-cut burgundy bikini, Kourtney ensured the camera caught her best angle for the shot which she later uploaded to Instagram.

And needless to say, her seemingly inflated behind has got everyone talking.

"So she finally turned into Khloe and Kim,” commented one Instagram follower, referencing her siblings' famous behinds.

"I don't know if that's real???? But its real nice,” added another.

While Kourtney hasn’t responded to the speculation that she’s succumbed and given her butt a surgical boost, Khloe reckons she loves being the subject of such gossip.

“Kourtney said, ‘I got so happy because someone said I had butt implants.’ And I was like, ‘Doesn’t it make you feel good?’ She’s like, ‘I really feel good. I’ve got to keep it up!’” Khloe previously told Redbook.

Meanwhile, having lost a whopping 35lbs since giving birth to third child Reign in 2014, Kourtney has been bestowing her wisdom on the masses.

In a post titled How to Look Good Naked, the 38-year-old revealed she keeps her skin baby soft by slathering face cream on her whole body, paying ’special attention’ to her hands and feet.

She also believes in quaffing an ounce of water for every pound that you weigh to "hydrate from the inside and out,” and sleeps in silk PJs on a silk pillowcase because the material is “hypoallergenic and doesn’t dry your skin out the way cotton does."
