No, no, it's not what you think. She didn't shave her head again. At Britney Spears' Oakland, California concert on Wednesday night, some of her hair extensions were ripped out in the middle of one of her songs. Check out the video here. OUCH! Either she needs to hire a new hairstylist to make sure those things stay in better or a big clump of hair was probably taken out with them and that calls for a major, "OUCH!"
So what exactly happened? It basically looks like she was lifted from a couch during a trapeze stunt and her hair may have gotten caught on something. Britney has had a few 'oops moments' at her concerts but they've mostly included the star yelling out weird obscenities or phrases to the crowd.
