Can you imagine if this was actually posted by Selena???
But no, it definitely wasn't as you can tell from the post.
The images are from a trip Bieber took to Bora Bora back in October 2015.
He was caught by a paparazzi while skinnydipping outside his private villa.
Selena's Instagram was deleted 30 seconds later in order to kick the hackers off the account, but it's back now with no nudes of Bieber obviously.
