Kim Kardashian West has hit out at claims she was photoshopped in Fergie's 'M.I.L.F.$' video.

The 'Keeping Up with The Kardashians' star says the reason her waistline looked so slim was down to wearing a corset and that she most definitely wasn't digitally enhanced in any way.

Taking to her Snapchat to share several behind-the-scenes clips from the 'My Humps' singer's music video, Kim captioned the posts: ''F***kYoPhotoShop #CorsetLife (sic)''

The 35-year-old beauty felt the need to defend herself after fans took to social media speculating she had been digitally altered.

It comes days after Kim laughed off rumours she wears butt pads to enhance her famous booty.

She previously explained: ''A couple years ago, I wore a skirt in Miami that was totally sheer. I had no idea it was SO see-through on my butt. I definitely never want that to happen again, so now I always wear shapewear.

''Sometimes, they have a sheer cutout like these capris from Body Wrap, so that's actually what you're seeing in the picture at the top.

''So, the fact is: I don't wear butt pads! At this point, I think everyone has seen my butt naked and knows I don't need them, LOL! (sic)''

Kim - who has North, three, and six-month-old Saint with her husband Kanye West - also revealed the secret to her perfect curves is ''No days off'' in the gym.

The brunette beauty was joined by Fergie, 41, and new mums Chrissy Teigen, Ciara and Alessandra Ambrosio in the music video.
