Last week, they posted another set of photos on a similar pink set, featuring them in blush colored bodysuits of a similar aesthetic.
One image features Kardashian posing on a hot pink motorcycle.
But the Keeping Up with the Kardashian stars received backlash from fans who accused them of using too much Photoshop on the images.
One fan commented: 'I didn't even realize it was Khloé and Kylie.'
Another asked: 'Where is Khloé?'

The new collection features one highlighter, two liquid lipsticks, a lip liner and the Koko Palette with nine shades of matte and shimmery eye shadow.
This collection marks the third collaboration between the two sisters.

But fans and followers are patiently awaiting the long-anticipated Kylie Cosmetics x Kendall collection, as Kendall is the only sister in the Jenner/Kardashian without her own Kylie Cosmetics products.
Last week, Kylie posted a day-in-the-life video that showed her meeting with Kendall as they teased the collaboration. Before showing a brief clip from the meeting, Kylie said: 'We have a collab coming.'
