She's biting back!

After online commenters noticed her super trim figure during a cameo in Fergie's new "M.I.L.F.$." music video, Kim Kardashian is slamming rumors that her itty bitty waist was Photoshopped.

In the video, the Keeping Up With the Kardashians star wears a tight shirt that reads "got milf," as well as a pair of itty bitty faux jean shorts. Of course critics took aim at the reality star for her small waist, claiming that it was Photoshopped.

However, the 35-year-old took to Snapchat to hit back, sharing a behind-the-scenes footage from the music video's set with the caption, "F--kYoPhotoShop #CorsetLife M.I.L.F.$."

So we guess that settles it! No Photoshop just a super intense corset that moves around your organs so that you can look freakishly thin!


Kardashian, who has a three-year-old daughter North and seven-month-old son Saint, appears in singer's video, along with fellow hot Hollywood moms Chrissy Teigen, Amber Valeta, Alessandra Ambrosio and Ciara.

The whole thing is majorly racy -- at one point Kardashian goes nude in a flesh-colored bra, as she showered with milk. Sounds like an average day for a hot mom!
