Kendall Jenner is getting in on the sexy gym selfies.
The 18-year-old reality star posted a new snap of her and sister Kim Kardashian during a workout -- both of them showing off their tight tummies and rear ends by the free weights.
"Barging in on Kim's booty selfie," Kendall posted with the photo.
The picture comes a week after Kim shared a similar shot with BFF Blac Chyna, a photo many online fans accused her of Photoshopping.
The new mom slammed the online haters on Twitter on Friday.
"It sucks when people make up surgery or photoshop lies when I am so disciplined & work so hard," she wrote yesterday.
"Just trying to motivate others & show anyone struggling with weight they can totally achieve whatever they want if they are dedicated," added Kim.
Well, we don't see any signs of Photoshop in this pic, do you? Kim's looking great!
