Miley Cyrus took it off!

A few inches off the bottom of her hair, at least.

The 17-year-old ditched her waist-length extensions for a lighter, shoulder-length wavy hairdo, which she debuted at the MuchMusic Awards in Toronto, Canada, Sunday night.

Cyrus, who co-hosted the show, also stripped down to a skimpy, mesh leotard to perform "Party in the USA." Just a few days ago, she declared, "I'm not trying to be slutty."

She defended the look to UsMagazine.com backstage. "I think that's fine. I just love performing. I definitely just feel most comfortable. I don't take myself too seriously."

"We are up there just dressing up; we are just having fun," continued Cyrus, who donned a white leotard for her second performance of "Can't Be Tamed." "It's about the girls and guys who are living their dream playing dress up. I don't walk around in a bikini and bright red lipstick all the time. Cause that's just who you are when you are performing and what goes into that song."
