According to reports from heat magazine, and her own anecdotes, it's believed that CBB4 winner Chantelle Houghton is bulimic, and suffering from a serious eating disorder.
This is such a shame - she always seemed such a healthy and beautiful girl, but I think things with Preston have been hard for her lately - are they on or off by the way?
I hope she gets well soon, and can find the help she needs to get her on the road to recovery.
