Last Friday night, yeah we danced on tabletops and… dyed our hair? Maybe that should be the new version of Katy Perry’s “T.G.I.F” because she can’t seem to stop switching up her hair color. It’s blonde, it’s black, it’s red! Now she settled on a bubblegum pink. To be honest, we aren’t surprised she changed her ‘do because frankly, she’s one of the few people on this planet that can rock every shade under the rainbow.

Here’s the singer with her new hue. It sort of looks like she dipped her head in a cotton candy machine, no?

This was Perry’s hair before she went pink. She debuted the buttery blonde shade at the premiere for The Smurfs on July 24. What a quick change!

Just a month before The Smurfs, Perry sported a dark autumn hair color, a much more natural choice than her flashier tones.

OK, this might not be in her typical color wheel, but it’s not unusual for Perry to sport a bright blue ‘do for her concert performances.

Dark ravenous black is the color Perry has worn for the longest (at least recently) and has proven to be a beautiful shade for her skin tone.

Then there was the multi-colored highlights she showed off at the 2010 MTV VMA Awards back in September. (Sort of looks like a predecessor to Lauren Conrad’s dip dye, huh?) Whew, we have trouble keeping up! The only things that changes more often than her hair are her crazy outfits! Which look of hers do you like best? Any that you’re willing to try out?
