We've seen it a lot in the past few weeks—stars swapping their hair color for a new summer 'do.
Next up, Hayden Panettiere. But it seems the Heroes star couldn't quite make up her mind when deciding what color to choose.
So, she chose them all.
As a result, Hayden is currently rocking rainbow-colored tresses. The 22-year-old tweeted a rather intimate picture of herself and a female friend saying, "Me and my BF Allie finally gettin' some play time."
Now, the star's colorful hair matches her notoriously colorful personality.
