Cue the blond jokes, because two hot stars are sporting newly golden tresses!

Katy Perry's hair went through another transformation this weekend. The singer ditched the pale pink tones on her recent shorn 'n' chic bob—which was actually a happy accident, her stylist said—for straight-up yellow hair with a few blue streaks, which she debuted while hosting Saturday Night Live in New York.

But don't blink or you could miss it, if the "Hot 'n' Cold" singer continues to change her hair at this rate!

We Bought a Zoo star Scarlett Johansson also revealed some newly lightened locks while promoting her new movie on the Today show yesterday. Back in May, the actress had gone ginger for a movie role, but she switched back to a dark ash blond that we're loving.

Well, it's working, because Scar looked gorgeous and glam with the curly 'do.
