Miley and her hair: BEFORE.

A lot of very important things have happened in the past 24 hours: One Direction and Jessie J performed at the London 2012 Olympics Closing Ceremony, and the Spice Girls reunited (!!!!!!!) at the London 2012 Olympics Closing Ceremony. But what are we freaking out about right now? All of that stuff AND the fact that the newly blonde Miley Cyrus GOT A MAJOR HAIRCUT.

Check out more photos of Miley's dramatic new haircut after the jump.

Miley: AFTER!

Miley recently tweeted a shot of her and hairstylist Chris McMillan as he was about to, quite literally, chop off all her hair. After that, Miley's Twitter feed went radio silent, but a few hours later, she reemerged sporting a totally rocker-chick pixie cut. The "Party In The U.S.A." singer then went on a photo spree, posting several shots of her new 'do, followed by an excited tweet stating, "Never felt more me in my whole life." We totally applaud your bravery, Miley! We're HUGE fans of Miley's new look and totally sign off on this as the ultimate wedding hair.

Oh don't play so coy, Miley, you look FANTASTIC!
