And by on fire, we mean she dyed her hair "flame" red. GET IT? Okay.
Kate Bosworth has recently taken her hair from its light blonde to a tawny, rather sexy red.
It was most likely for her role in Still Alice currently filming in Manhattan, and it's hot! Red-hot, you might even say, if you were into puns!
Anyway, the actress joins Britney Spears as the latest Hollywood celeb to go scarlet.
Personally, we heart it, and since it's a lighter red, it probably won't fade as quickly. Hurray!
