Though it's hard to see Sienna Miller as anything less than beautiful, according to Sienna herself, she's fallen victim to some seriously heinous haircuts.

"First I experimented with rave colors, dying it pink, then pink with white streaks, then green. I even tried cornrows, which was not a good look on me, especially as I had braces at the same time," Sienna tells The Telegraph.

But by far her worst haircut came when she was 16, when she attempted Winona Ryder's signature pixie cut.

"Then, when I was 16, I took a picture of Winona Ryder into a branch of Toni & Guy in an effort to achieve her pixie cut. But when I walked out I looked as if I had a helmet on," she recalls. "My boyfriend at the time opened the door and closed it in my face. I don't think I'll be trying that again."

Somehow I don't think Sienna with a Michelle Williams cut, or not combing her hair for that matter (see picture above), is a deal-breaker for most guys.
