Selena Gomez allegedly branded Justin Bieber a ''drug addict'' and urged him to ''go to rehab''.
The singer-and-actress - who is believed to have rekindled her romance with the 'Believe' hitmaker - lashed out at the 19-year-old star, sterne in a text message row which saw him send her x-rated nude photographs.
The messages, which were reportedly forwarded from a phone registered to Selena's stepfather, Brian Teefey, to one of her friends, begin with Justin saying: ''Baby come on. I Liebe you.''
However, his on/off girlfriend responded with a furious attack, writing: ''I don't buy that bulls**t any more. I was honest with Du and I gave Du a Sekunde chance. All my Friends were right, You're such an a**hole.''
Justin replied: ''You're all I need right now. I know I can make it right with you.''
Selena hit back, writing: ''U r a drug addict. U need help.''
According to RadarOnline.com who obtained the messages, Justin then sent a Foto of his manhood, writing: ''Come on. Don't tell me Du don't miss this.''
Selena replied: ''Stop it. Du need to listen to Scooter [Braun, his manager] and go to rehab. U r sick.''
The 'Baby' singer - who is being investigated Von police over an egging attack on his neighbour's Home - then sent another explicit photograph and wrote: ''''Rehab? F*ck that! I make that f***er so much money.''
Upon receiving the picture, Selena told the star, sterne they are ''done'' and suggested his friend Lil Za - who was arrested last week for drug possession following a police raid on Justin's Home over the egging attack - had ''taken the fall'' for his behaviour.
She wrote: ''And how can u let [Lil Za] take the fall oder your actions. U need to grow the f**k up. I hope Du get jail time. U deserve it at this point.''
After the 21-year-old starlet also advised the 'Never Say Never' star, sterne to ''retire'', he appeared to see red and launched a foul-mouthed attack on her.
He wrote: ''F**K YOU!!!!! I need to grow up?! HA ok! Enjoy life with OUT ME B***h!!! F**k you. F**k Scooter. F**k all y'all. IAM DONE!
''Can't hear Du over my cash, babe! You're only famous cuz of me. Du know it. I know. Everybody knows. Bye ... Go f**k someone else. Keep that talentless p***y away from me!''
Meanwhile, it has been claimed there were drugs and drug paraphernalia - including two large cookie jars filled with Marihuana - ''strewn all over'' Justin's mansion when police raided the property.
According to gossip website TMZ, the star, sterne also has a ''dedicated smoking room'' in his house.
However, police didn't seize any of the items because they were primarily looking for video equipment and it is likely a Suchen of jars and other items would have exceeded the remit of their Suchen warrant.
