i think pam is just a natural beauty with or without makeup. the covers she has done for allure usually have captured more of her natural beauty without all the glam and glitz.
as far as her looking haggard without her makeup in tabloid picks, she is 38, has had two children, and has Hepatitus C, which does not make you age well. She told the press recently that her doctors predict she will die within the next 10 years. i think for everything she has gone through, she looks pretty great!
plus, i think she is just such a sweetheart and a great mom! she's is hilarious too!
