Yeah, I remember the scene from "Sirens" when one of the models said "You dream of laying on your back while he licks your bellybutton".
There's also a line in the movie "Blame It On Rio" where a girl admits that "It will take weeks to get all the sand out of my bellybutton".
There's a little movie I like called "Playing Mona Lisa" where a girl admits she like to have her boyfriend stick her tongue in her bellybutton.
There was a time Christina Ricci was on "Ally McBeal" and said she had a thing for bellybuttons and offered to kiss Ally's.
There was one interview with Halle Berry where she admitted she was "a bellybutton girl".
During the release of the S Club 7 movie "Seeing Double", Tina Barrett wore a dress that showed off her stomach and she admitted "You can see my bellybutton". Speaking of which, the plot of that movie is that the band members are cloned and the clones don't have bellybuttons, so the girls say "bellybuttons" more than once.
During an interview, Katherine McPhee once admitted that her bellybutton is an outie and can be pulled further out of her stomach, which she then did.
Olivia Munn mentioned on G4 that her bellybutton is very high-set on her stomach and she then showed it to the camera.
Miranda Kerr mentioned twice that her innie could be pulled into an outie, which she showed off both times.
Rose Mcgowan said "bellybutton" twice during an episode of "Charmed" because she met a man who didn't have one.
Those are all the ones I can remember. If the navel fetishism screenplay that I'm writing gets made, it will have the word "bellybutton" being spoken so many times, you can make a drinking game out of it!
