Poor, SELENA GOMEZ! What a bad start to her week!

Some jokers decided it would be funny to hack into the superstar's Instagram account and post nude photos. But, not just ANY nude photos, but of her former flame JUSTIN BIEBER. 

The three hackers admitted to the post by signing with their IG handles. Total jerks. 

The *ahem* censored photo is below... 

Selena deactivated her IG account almost immediately.
