London, April 28 : Singer Jessica Simpson says she brushes her teeth just three times a week because she doesn't want to mess with the whiteness.

"My teeth are so white and I don't like them to feel too slippery, but I do use Listerine and I do floss everyday. But, I don't brush them everyday," contactmuisc. com quoted her as saying.

The 29-year-old regularly flosses and uses mouthwash to keep her breath fresh, but she refuses to brush daily with toothpaste.

"I'll use a shirt or something. I know it's gross but I always have fresh breath," she said.(IANS)
