Kim Kardashian West has confirmed she gets butt injections.

She said: "Every few years I get a cortisone shot. I just got one as my psoriasis was so bad in Vegas. "That's a little unknown fact of me - I have to get cortisone shots every few years."

The raven-haired beauty first learned she had the condition because her mother Kris Jenner spotted a rash on her leg.

But after Kim - who has kids North, three, and Saint, eight months, with husband Kanye West - had her first cortisone shot speculation spread that she'd had butt implants as pictures emerged of her with a dent in her derriere.

Speaking on a live stream on her official website, she recalled: "I went to go get a cortisone shot in my butt.

"I lived right behind Kitson [a boutique]. One of my neighbours was a dermatologist at Cedars [Cedars-Sinai Hospital].

"I go in there and he's like, 'There's a one in a billion chance that you will get a huge indent in your butt.' Of course I get a huge indent on my butt.

"There is a picture of me in Miami wearing an electric blue dress, and another picture of me walking down Robertson.

"You see the indent. And I think that's when the rumours started, 'She's had implants.' "

Kim admitted she has "learned to live" with the condition and that it "doesn't bother" her too much.
