Britney Spears Hair Getting Blonder

During her latest visit to the racket store, the brunette Britney Spears showed that she might change her hair color soon.

If you see in the picture she already has some kind of blond hair growing by her head sides. Is she planning to change her hair color back to blond or is this just an extension problem?. Probably answer number 1, since meanwhile Miss Spears was seen wearing a pink wig. Weird Huh?
