For the first Twilight flick Nikki, who plays a Rosalie Hale, had to dye her hair blonde which turned out to be a disaster.
She explained at last week's premiere:
"Most of my hair fell out, which is why they wigged me. It’s hard on the hair. I don’t miss being a blonde. I do miss Rosalie."
We think she looks better as a brunette anyway.
