It's been said that it's a woman's prerogative to change her mind, and apparently Miley Cyrus is no exception.

Last week we reported (and applauded) that the 17-year-old pop star had ditched her lengthy hair extensions and was sporting a chic -- and much more natural -- 'do.

But maybe we were the only ones who loved it because industry insiders now say Cyrus has returned to her hip-length locks. Not only that, but you won't believe how much she paid for them!

A cool $24,000. (Nearly as much as her "Can't Be Tamed" corset!)

Sources told InTouch Weekly that "Miley bought the best hair possible, and then had it dyed to match hers exactly. Her hair is an investment."

For that amount of dough, is it any surprise that Miley reportedly had the extensions flown in from Italy to New York? She then had them delivered to hairstylist Kristina Barricelli at New York City's expensive Gemini 14 salon (which also services Brandi Irwin, the woman who spends $47,000 per year on her hair). From there, Miley's new hair -- and her hairstylist -- were flown to L.A., where it was put on.

Whew. Those must be some locks.

But really Miley, we liked your shorter 'do better.

Meanwhile, in other former Hannah Montana news, take a look at what she wore to the Canadian music video awards!
