She is the fifth most popular celebrity on Instagram with almost 100 million followers, just behind Ariana Grande, Beyonce, Taylor Swift and Selena Gomez.
But unairbrushed pictures of Kim Kardashian in her bikini may cost the social media queen her mighty online presence as 100,000 fans have unfollowed her on the picture-sharing site.
Many claim that the unflattering paparazzi snaps are proof that Kim, 36, has been Photoshopping her Instagram images for years.
Kim was enjoying a girls' holiday in Mexico to celebrate her sister Kourtney Kardashian's birthday this week when photographers snapped her in a variety of skimpy bikinis.
The pictures showed off Kim's natural figure and revealed her curvaceous behind which was a little dimpled with cellulite.
But fans have seized on the difference between the paparazzi pictures and the snaps Kim posts on social media herself, claiming that Photoshop and even plastic surgery are behind the difference.
The mum-of-two was blasted on Twitter and Instagram with former fans declaring her 'fake'.
