Miley Cyrus’ hair: It’s platinum blond, and mostly gone!

Miley Cyrus has changed her hair — dramatically. She’s gone for a platinum blond power-pixie cut, and she’s rocking it.

And it turns out it’s something she’s wanted to do since she was touring as Hannah Montana.

Following in the footsteps of the likes of Anne Hathaway, Emma Watson, Michelle Williams and more, the 19-year-old pulled off a dramatic makeover, the transition to which is shown above. Helping Cyrus get the look she wanted was stylist-to-the-stars Chris McMillan, who can be seen in a picture tweeted along the way.

� ♥ ♥ ♥ ♥ feeling so happy in my skin,� Cyrus said late Sunday night, accenting the tweet with a photo and a flurry of hearts.

Still, she battled some haters, fighting back by repeating that age-old phrase about opinions being like, well, something else that everyone has, and reinforcing that she’s digging the new look. “LOVE my hair ♥ feel so happy, pretty, and free,� she tweeted.

One would think that this would be bad news for the Miley Cyrus’ Bun Tumblr blog and Twitter account, both of which celebrated Cyrus’ habit of pulling up her long hair on top of her head, but the @mileycyrusbun account on Monday was celebrating the singer’s new ‘do in a series of tweets.

“Don’t worry, Miley Cyrus’ Bun is not over. Her hair will grow, and please guys she’s Miley Cyrus. She can make it everywhere everytime. This’ll be forever Miley Cyrus’ Bun’s TwitterPage. Still love her and happy that she feels herself confident and beautiful. Because SHE IS.�

The cut apparently is the realization of a years-long dream. When a 15-year-old Miley gave “Good Morning America� a tour of her dressing room in 2008, she gestured toward a picture of 1960s model Twiggy, known for her blond pixie hair.

“Twiggy. One day I’m gonna cut my hair like that,� she said. “I know I am. I will one day.�

Mission accomplished.
