I read somewhere that a woman is most beautiful at 31 and then she starts declining.  Ouch.  I just turned 30.

For men I remember that age being slightly older.

Well, if you check out this video, you'll notice that these celebs don't seem to get any older at all.  Ever.  Not fair!

I'm not sure if they're getting a little help from potions, cremes, and doctors, or if they just have great genes!
