More Kardashian Kontroversy: Sisters' 'Killer Curves' Allegedly Photoshopped On British Magazine Cover

It's not the first time a magazine has been accused of Photoshopping their cover girl, and it probably won't be the last.

This time Kim, Khloe and Kourtney Kardashian are under fire for their UK cover of Notebook in which all three women were allegedly slimmed down.

All three sisters appear to have had a nip or tuck by the digital program.

Khloe, 29, seems to have a longer neck than usual on the cover and her waist looks cinched.

Meanwhile new mommy Kim, 33, looks like her cheekbones were sunken to give her face a thinner look and her shoulders look more defined than in recent photos.

Known for their hour-glass figures, the Kardashian sisters look less shapely than usual — even Kourtney's already trim waist looks like it was taken in for the cover.

Fans noticed the tweaked cover and sounded off on Twitter.

"The Kardashian sisters cover Notebook magazine in an issue talking about their curves which are absent from the overly retouched cover," one user noted.

Another blasted the cover writing, "Photoshop fail! Kardashian curves tweaked to create skinny bodies for mag cover."
