Katy Perry
debuted a new 'do this weekend -- and not only was it a lot less pink, but also A LOT shorter!

The singer, who's been experimenting with long pink hair since the MTV VMAs back in August, showed up to the 3rd Annual "Change Begins Within" Benefit in L.A. this weekend with blonder, shorter tresses.

While it's definitely a different look for Katy, it's one we're really liking. What do you think?
