Jessica Simpson visited the Tonight Show Tuesday night where she told Leno that she is addicted to Nicorette despite having never smoked a cigarette. She said she had been chewing it and put it on her water bottle before she came on set.
"The first time I ever chewed a piece of Nicorette gum one of my close friends' mother gave it to me," she said. "I think she thought she was giving me a piece of regular gum. I was chewing it and it was like a party in my mouth. It was like fireworks and 'Oh my god, I'm talking a million miles per hour and I love this gum and what kind of gum is this? I have to have this gum.'"
Jessica will also appear on the Ellen DeGeneres show Wednesday. She tells Ellen that she is still single but "mingling around."
"I mingle around very privately," she said. "I have ways in and out of my house and certain places that I go that are private just so I can have a normal life. I'm still out there and bring normal."
Ellen asked Jessica why she only brushes her teeth three times a week.
"My teeth are so white and I don't like them to feel too slippery, but I do use Listerine and I do floss every day," Jessica said. "But, I don't brush them every day. I'll use a shirt or something. I know it's gross but I always have fresh breath. It's really weird, but I have great breath."WATCH:
