The excitement surrounding the Kardashian/Jenner sisters following the pregnancy rumours of Khloe and Kylie has since turned to desperation by fans to catch a glimpse of the siblings and their bumps. However, the youngest sibling allegedly pregnant, Kylie, has hit out at media organisations who have taken a recent picture of her and accused them of photoshopping the image.

The 20-year-old was pictured boarding a private jet with her sisters Kendall Jenner and Kourtney Kardashian on Sunday morning and the snaps appeared to show the reality star with a baby bump under her baggy hoodie and jogging bottoms.

However, now she has hit back at the claims, taking to Twitter to tells paps that if they are going to alter images of her then they need to ‘check for the crooked lines in the background’.

"First of all if you’re going to photoshop my photos blogs/paps!! Check for the crooked lines in the background. 2nd photo is clearly altered (sic)," she wrote on Twitter alongside four images taken by X17.

In response, X17 have said the images are 100 per cent real. The company said: "No Photoshop, #nofilter, no additives, no preservatives - all organic and all REAL!"

They added: "We’re totally cool with Kylie pretending she’s not pregnant so she can get paid off by some magazine or TV show to make a big reveal but let’s get real, people, we KNOW she’s with child and we KNOW who the daddy is."

Kylie, 20, has kept quiet about her rumoured pregnancy as has her older sister, Khloe, 33, about whom speculation began to swirl just days after news broke of Kylie’s believed expectant state.
