HAPPY BIRTHDAY AND CONGRATS!

Not these skanks again. Maybe someone will give them a much needed hairbrush for their birthday.

I don't think I would consider these two "skanks"

YAY for them !! Happy B`Day

Hahaha funny.. olsen baby teeth? happy b-day MK&A!

the girls are bazillionaires and they can do whatever they want whenever they want - dress like elvira every damn day for the rest of their lives if they want. they don't need the money or the publicity and are still good role models (for the most part) to the young girls who look up to them and by their videos, makeup, clothes, fragrance, etc. that's the girl power - happy birthday!!!

I SO can't believe they're 21!

go shorties it's your birthday

i can't believe they're actually older than i am. we're only a couple of months apart, but when i look at them they seem so much younger. congrats to them anyway. love them

HAPYY 21ST BIRTHDAY!!!!!!!!!!!!!!!!!!!!!!

Happy Birthday to the Olsens!

Happy Birthday Girls - all the best wishes....have you noticed that these 2 haven't really caused headlines while they were growing up (unlike some other people)

Happy Birthday!I feel old now.I remember watching them as little kids on Full House.

awww happy birthday to them!

They look too young to be 21. It is good that they seem responsible-based on their business decisions.

WHAT??? SO YOUNG????

gud for them!! r ther stil spots open in rehab?...

YAYYYYYYYYYYYY !
