Last night we watched as some of the biggest names in the entertainment industry walked the red carpet of the Met Gala. We saw Beyonc茅鈥檚 barely-there dress, Sarah Jessica Parker鈥檚 insane headdress and who can forget about Rhianna鈥檚 monumental gown (you probably saw it transformed into a pizza or an omelette on the Internet this morning). As far as hairstyles go, Katie Holmes鈥 fresh cut was causing the most commotion 鈥 that is, until Miley Cyrus arrived.

Always one to take a fashion risk, Miley showed up to the 2015 Met Gala rocking icy blue hair. But wait, it wasn鈥檛 just blue it was blue and sparkly! Sorry, Hilary Duff but Miley definitely just snagged the award for best mermaid hair.

Considering Miley鈥檚 rambunctious style we can鈥檛 say we鈥檙e even a little bit surprised that she traded her bleach blonde locks for a colorful hue. In fact, we鈥檙e surprised she waited this long. Cyrus also received some attention last week over a snap she posted showing her rocking bright pink armpit hair. While dyed armpits + a new hair color probably would have sent the Internet into total chaos, it looks like she opted to keep the former hidden for the evening under her studded Alexander Wang gown.

It鈥檚 unclear whether the new color is temporary or permanent (we鈥檒l have to stalk Miley鈥檚 Insta for a post-Met selfie to figure that out), but either way we鈥檙e major fans. What we鈥檙e most eager to find out is if the luminous element of the new color sticks. If it does we kind of need to know how she managed that ASAP. Could shimmery hair be the next evolution of rainbow-colored locks? We really, really hope so.
