JLH saying that she doesn't understand what the fascination with her boobs is about, is equivalent to Bill Gates wondering aloud what all the fuss is about concerning the fact that he is the richest businessman in the world.
If you have always had something, it may be hard for you to appreciate the POV of someone else, who doesn't have that thing.
And besides, as Colette said, JLH is a girl -- she isn't going to lust after HERSELF now, is she?
That said, JLH should watch who she says that to -- a jealous flat-chested gal may scratch her eyes out
