Olivia Newton-John'S daughter has delayed the release of her debut album amid speculation she is suffering from an eating disorder. The release dates of 20-year-old Chloe Lattanzi's debut single and album, which reveals the singer/songwriter's darkest days, have been pushed back in order for her to deal with her health issues. Sources tell Sydney, Australia's Daily Telegraph she is fighting to avoid a relapse of body image issues she endured as a teenager and her mother is desperately trying to help her beat the illness permanently. A source says, "Olivia is a survivor. Chloe is a fighter. They're inseparable and they're winning this." Lattanzi has spoken out about depressive episodes in the past and has been treated by specialists in the US. Last March (06), she addressed widespread rumours that she was battling an eating disorder and admitted she had weight issues as a teenager, but denied it was a problem saying, "I went through a phase in my life where I know I was too thin - I acknowledge that. That was a very stressful time in my life, and it has passed now."
