'I Don’t Brush My Teeth'

Is this really something you want to share with a radio audience? No wonder she seems to constantly have problems with her love life.

Guess those teeth weren’t made for brushin’.

Jessica Simpson has only a nodding acquaintance with a toothbrush, the singer told iheartradio on Thursday.

"I don’t brush my teeth," said the "Irresistible" singer, according to UsMagazine.com. "No, really!"

"I just use Listerine - and sometimes I'll use my sweater," she added with a laugh.

"I do brush every now and again, but my teeth are extremely powerful. Fine, maybe when I'm 60 I'll be all, ‘ow!’"
