Here's a photo of Miranda Kerr pulling her foot over her head for no discernible reason while wearing only a skimpy bikini; here, a cheery beach snap of Alessandra Ambrosio standing on the sand in a high-cut silver swimsuit, legs uncomfortably askew; and oh look, it’s Lady Gaga contorting her body into a strange and unnatural pose… on a paddleboard.
All of these are genuine posts, with tens of thousands of likes between them. You may have even double-tapped, yourself. Gaze at them a little longer, however, and they just start to look, well, weird.
It turns out that attractive female celebrities, for some time now, have been sharing some very strange photos of themselves on social media, and getting away with it.
Sure, they'll occasionally receive criticism for what they're wearing - or not wearing, as is more often the case - or for promoting unhealthy or unobtainable standards of physical beauty. Yet no-one seems bothered by the fact that they're inexplicably sat in a sink, or doing a handstand while kissing their "boyfriend".
Enter Celeste Barber, who has devoted her own Instagram account to calling BS on these ridiculous celeb snaps, by recreating their famous poses and sharing her versions alongside the original images.
