U.S. pop singer Jessica Simpson says she barely brushes her teeth, choosing instead to use antiseptic mouthwash for her dental hygiene efforts.

The New York Daily News said Saturday, citing a report by Us Magazine, that Simpson admitted she embraces questionable dental hygiene efforts that could potentially haunt her later in life.

"I don't brush my teeth," Simpson, 29, said. "No, really!"

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

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

The "Do You Know" singer also spoke about her romantic history, which has ranged from a relationship with singer John Mayer to her former marriage to singer Nick Lachey.

"In relationships, in general, going through a divorce and going through very public breakups... you don't want to disappoint people who are rooting for you to be successful in love. I just have to find the right man," Simpson said.
