Jessica Simpson has never been one to shy away from the press, often speaking her mind quite frankly about her love life -- and even her hygiene habits!
The singer revealed a very personal tidbit to iheartradio Thursday, saying, "I don't brush my teeth .. No, really! "I just use Listerine -- and sometimes I'll use my sweater," she chuckled.
While she seems perfectly fine detailing her own intimate moments, she expects discretion from her suitors. Just prior to the iheartradio interview, she said of ex John Mayer on David Letterman, "normally you would think that somebody you care about would keep those intimate details to himself..." in reference to his Playboy comments. "I mean, it was definitely a compliment, in a way, but I don't really want people to know that about me."
