Beyoncé Knowles doesn't wash - so she can keep her skin flawless.
The beautiful singer-turned-actress has revealed her top beauty tip for perfect skin is to never wash your face with soap or cleansers.
She told Top of the Pops magazine: "I don't wash my face with soaps or put on lotions. It's the truth."
Beyoncé, who is rumoured to be tying the knot with her rap star boyfriend Jaz-Z in November, also insists it is important to eat the right foods and not nibble on fatty snacks if you want to have skin as beautiful as hers.
She added: "I think eating healthily and staying away from bad food is also important."
However, Beyoncé has been treating herself to junk foods lately after going on an all-liquid diet so she could drop two dress sizes for her role in new movie 'Dreamgirls'.She revealed: "The best thing about the diet was coming off it and eating what I want - doughnuts, chicken it's great!"
