Oops she did it again!
After years of staying loyal to her signature blond locks, Britney Spears is back to being a brunette.
The 37-year-old also revealed the muse behind her new look, adding "Yes, my sister inspired me to go dark !!!!!!!"
Earlier this summer, Jamie Lynn Spears went from blonde to brunette, and it looks like her older sis couldn't wait to follow suit.
The pop sensation's boyfriend, Sam Asghari, gave Spears his seal of approval in the comments, writing, "Beautiful blond or black."
We've seen Spears go through a whole spectrum of hair colors over the years, but she always seems to go back to brunette at one point or another. Still, we wouldn't be surprised if she switches back to blonde soon enough!
