Justin Bieber, Selena Gomez and her 125 million Instagram followers had quite an interesting day.

Selena Gomez's Instagram account had to be abruptly taken down after it got hacked. Well, the hacking wasn't the worst part; the people behind the hack posted a very explicit picture.

Someone posted Selena's ex-boyfriend Justin Bieber's nudes on her Instagram account with the caption “LOOK AT THIS N***A LIL SHRIMPY.”

The NSFW pictures of the singer posted are the very same pictures that were published, without Justin's permission, about two years ago after his trip to Bora Bora with beauty blogger Jayde Pierce. 

Back in 2015, the censored pictures were originally posted in the New York Daily News, but eventually, the uncensored pictures also spread on internet somehow. Talking to Access Hollywood back then, Justin said that the nude photos being leaked made him feel “super violated” and, “Like, I feel like I can't step outside and feel like I can go outside naked.”

He added that, “You should feel comfortable in your own space…especially that far away.”

Some people thought the hack was quite funny.

But, what I don't understand is how can someone hack the most followed person Instagram that easily. 

Selena coming up with a new password right now, probably:
