Jessica Simpson against brushing her teeth every day

Jessica Simpson doesn't brush her teeth every day – because she doesn't like them to be too "slippery".

The blonde beauty avoids scrubbing her gnashers more than three times a week instead choosing to floss.

During an appearance on 'The Ellen DeGeneres Show' to air today (28.04.10), she revealed: "I don't do it because 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 every day.

"My lips just slide all over the place... I can't catch up with my mouth.

I need a little coating."

Despite her sporadic dental hygiene, Jessica is adamant she always has pleasant smelling breath.

She added: "I know it's gross but I always have fresh breath. It's really weird but I have great breath."

The 29-year-old singer also revealed she is on the lookout for a new man and insists a guy doesn't have to be famous to date her.

Jessica – whose exes include John Mayer, Tony Romo and former husband Nick Lachey - said: "They definitely have to understand my life and what I put up with and what I deal with. Being scrutinised publicly... that can definitely make or break a relationship and you have to have that strong foundation... so I have to have somebody that understands that kind of lifestyle."
