One of Lily Allen's best-known songs is called "Smile."

Well, the British pop wreck recently gave celebrity hairstyle watchers a lot to smile about when she upgraded her raggedy-ass pink 'do for the healthier and cleaner, chestnut-brown cut seen below (in London on Monday).

Before that, Allen had gone from pink to blonde, then back again!

  • Lily Allen Close Up
  • Lily Allen Bangs

Just two of the many hairstyles of Lily Allen.

You know what they say. Nothing makes a pop singer look new, reinvented and 100 percent stable like a new blonde weave! That or a conservatorship.

Give Lily Allen credit.

When this singer makes a change to her hairstyle, she doesn't just go with bangs. Or curls. Or any sort of bun.

No, when Lily Allen wants a new look, she goes all the way. With that in mind, compare the pictures below and let us know which color hair you think looks best on this wild crooner:

  • Lily Allen Pink Hair
