Demi Lovato's rumours...what??

Demi Lovato's rep has strongly rubbished rumours she's in rehab for drug and alcohol addiction.
The Camp Rock star, 18, pulled out of her joint tour with the Jonas Brothers last week to enter a clinic.
But since then, wild and unsubstantiated claims have been made that Demi is seeking treatment for substance abuse. 
But her spokesperson has set the record straight now.  
'Demi Lovato is not in treatment for drug or alcohol addiction,' her rep tells TMZ.
'As we have said since she entered treatment last week, Demi decided to seek help for emotional and physical issues she has battled throughout her life.
'She has taken this step in order to get her life in order. While we know many are interested in Demi and her life, we do ask for a modicum of privacy during this difficult time.'
Demi's spokesperson has not given any further details about what her 'emotional and physical issues' are.
