Jessica Simpson -- Guess What I Did To My Mouth?!

Non-habitual toothbrusher Jessica Simpson claims she actually cleaned her pearly whites before heading to the airport yesterday -- a feat so rare, that her mother claims she had to take pictures!

Of course, Jessica recently admitted that she only brushes about three times a week -- because she doesn't like the way clean teeth feel in her mouth.

But yesterday in NYC, Jess bragged about her clean mouth -- and her mother added, "I went over all of her hygiene habits, just so she can remember them".

Better 29 years late than never!
