By now everyone has seen and heard about Jennifer Lawrence's blond pixie cut.

But guess who is taking the blame for the hair disaster that led to the extreme new look?

Catching Fire director Francis Lawrence!

"She used to give me a hard time about the hair because I was always saying, 'Dye your hair, dye your hair. We need your hair dyed, no wigs!'" Francis told me while promoting the second installment of the Hunger Games franchise (in theaters on Nov. 22). "And then of course, dying her hair fried her hair, so she had to cut her hair."
