You probably know Katherine Heigl as the beautiful blonde girl on 'Grey's Anatomy'. You'll see a different side to her when she graces next months cover of In Style magazine: Her brunette side.

In the October edition of the magazine she says she would like to change her hair color in the show but the producers just won't allow it.

She also stated:

"To have these professionals turning you into someone else is pretty neat," she says of the transformation – especially when it came to her hair. "I've always wanted to be a brunette because in a town of blondes, it makes me look a little more exotic," she says.
