At a Golden Globes party Mary-Kate Olsen got tongues wagging when she showed off her skinny figure in a low-cut gown.
Her rep has slammed reports that she’s relapsed back into anorexia. According to her rep she hasn’t lost weight and is continuing treatment with the help of a therapist.
A friend of MK’s blames her blonde hair
“The blonde hair she has now makes her look skinny.” 
I'm sorry but how can a hair colour make you look skinny !!!!
