Black hair..!

thats not true ,they had never black hair....
ashley had in 2006 a dark hair color ,i think it was a chocolate brown ,but never black!!!

I think both have blond hair they once in a while they dye their hair

They do not have black hair, their natural hair colour is fresa blonde but they do dye it so thats why your sister may have told tu at the time where they dyed their hair black for a long time ;)
