Justin Bieber sexted Selena Gomez after she called him 'drug addict'

Justin Bieber has entered a bitter text row with on-off girlfriend Selena Gomez after she called him a drug addict and urged him to go to a rehab, and he sent her nude pictures of himself in reply.

According to Radar Online, the texts were forwarded by a mobile registered to Gomez's stepdad, Brian Teefey, to one of her friends.

Even though the texts started innocently enough, with the 'Baby' hit maker telling Gomez that he loves her, they soon turned graphic after the brunette beauty told him that she doesn't buy "that bullshit" anymore because he's an "a**hole".

Bieber appeared to be unfazed by Gomez's back lash and sent her a photo of his erect penis and asked her if she didn't "miss this".

Then, a furious Gomez told him to listen to his manager, Scooter Braun, and go to rehab because he is sick and needs help.

The teen icon lost his cool over the rehab comment and told Gomez to "f*** rehab and Scooter because he makes that "f***er a lot of money".

The text-message clash ended with Gomez telling Bieber that he needs to grow up, while Bieber replied saying that she was only famous because of him and he would like to see her live her life without him.
