This is probably a hair social media DON'T.

Katy Perry is under fire on Twitter after posting a video of herself snapping back at a fan who criticized her new short blonde haircut.

"Oh, someone says, 'I miss your old black hair. Oh, really? Do you miss Barack Obama as well?' Oh, OK! Times change, bye. See you guys later," the pop star says snarkily in the short clip.

Watch below:

While it must be frustrating having people constantly comment on your personal choices, many were taken aback by Perry's attitude, and hit back at the singer on Twitter for being insensitive and "extra"—and also for dragging Obama into the mix.

What do you think? Is the backlash warranted, or was Katy just making a poorly-received joke? Sound off on Twitter: @PopCrush
