Typical womanly wisdom goes that when your hair starts to gray, you do whatever needs doing to make it, uh, not. Unless you're Rihanna that is, who — at the ripe old age of 25 — has taken to Instagram to show off new dyed gray locks. "New color ice grey ish call it #Brr" the singer posted on Wednesday night, earning more than 300,000 double taps from her doting fans. She's since backtracked a bit, darkening up again and merely infusing her raven tresses with gray — we mean "brr" streaks. And she's not the only one who, in recent years, has taken a cue from the Bea Arthur beauty book and de-colored their locks. Scroll through to see nine of RiRi's contemporaries who, too, have decided to go gray before their time.
