Kim Kardashian accused of using Photoshop AGAIN as she flaunts major cleavage and impossibly tiny waist in bathroom selfie

Just a little over a week since her glaring Photoshop car fail, Kim Kardashian has been accused of altering one of her snaps yet again.

The queen of the sexy selfie, who hadn't shared a scantily-clad selfie on social media for at least a week, filled the void with a snap in her undies on Wednesday.

The mum-of-three, 37, took to Twitter to treat her 59 million fans to an outtake from a recent Calvin Klein shoot.

"Found this pic I took in the bathroom on set of My @calvinklein shoot," she wrote before saying it was actually an ad - though any excuse to post a semi-nude picture.

The reality beauty is posing in front of a mirror in less than glamorous bathroom.

Her high-waisted black knickers highlight her tiny waist and curvy hips, while she's showing off plenty of cleavage in the plunging black bra.

While most of her fans praised the hot shot, some of her followers didn't seem too impressed - and some were also quick to notice something slightly odd about the picture.

"Let's talk," one wrote alongside a zoomed in snap of a curve in the wall behind her just by her thigh.

A second sarcastically commented: "Photoshop goals."

Oh, and is that another curve in the wall?
