accents

I have mentioned this before but would like to ask again, how come after working in the US for so many years, dating American men, even living here I still can only understand every other word Salma Hayek says and about every 5th work Penelope Cruz says?

Also, has anyone noticed the accent on the woman in the Cadillac SUV commercials? Not the one with Dr. Addison Montgomery Shepard and the does your car turn me on commercials, the one with the brunette and the cup holders. It makes her so much hotter. Why is my accent a target for jokes and not a source of extra sexiness?
