Katy Perry has changed her hair up once again!

She cut her hair just in time for the Brazilian premiere of her 3D movie Katy Perry: Part of Me. She showed up on he red carpet with her new hair.

This time, it's jet black and cut to just above her shoulders. Before, Katy was rocking purple hair.

It's no surprise she's changed it though – Katy always likes to change her hair up every few months!

Wambie girls, what do you think of Katy's new hair?
