I think if you look hard enough you can spot "flaws" in anybody.
I have 1 eye slightly smaller than the other (well thats the most minor thing "wrong" with me - forget about the overweight, spotty, large pores, oily skin, etc etc etc).
I think its good for us to remember than celebrities are real people who just have a lot of money, lots of hairstylists, make up artists etc to make them look good whenever they go out. You only have to look at candid photos taken when they don't expect it to see that they are just normal people.
However - while we are on the subject:back2topic: - don't forget Victoria Beckham's bunions and a hell of a lot of celebs toes!!!!
