Willow Smith Shaved Head: Singer Debuts New Look On Twitter (PHOTO)

Willow Smith may be known for whipping her hair back and forth, but it looks like she's going to have to find a new signature catch phrase.

The singer, daughter of Will Smith and Jada Pinkett Smith, debuted a new, short look on her WhoSay page via Twitter Thursday. In fact, it looks like Smith ditched her hair altogether and is now sporting a shaved head, similar to her dad and brother Jaden's new looks.

Smith gave no explanation or reason as to why she decided to switch up her look, but she's certainly in good company. Last week, Cynthia Nixon debuted a new bald look, which she is sporting thanks her role in the Broadway play, "Wit."

Check out Smith's new look below, as well as other stars who have decided to ditch their 'dos:
