Olivia Newton-John's daughter Chloe Lattanzi has sparked reports she's losing her eating disorder battle after appearing "emaciated" at a post-Emmy Awards party in Hollywood.

The skinny singer, 21, was photographed at an Entertainment Tonight party on Sunday and left many onlookers asking if she was struggling with her anorexia fight. Lattanzi revealed she was anorexic late last year and has spent much of 2007 trying to overcome her struggles.

But Jack Strom, who represents both Lattanzi and her mother, tells the Sydney Daily Telegraph that the singer is "fine."

He says, "The last time I spoke to her and her mom was just a few weeks ago and she was fine. She's focusing on launching her music in the States at the moment. In the past (she) has always addressed this problem very openly. It's not something she's trying to hide and is dealing with in her own way in the media."
