Yes, that is Britney Spears and yes she is wearing a wig. Don’t miss judge this. Britney is not back to her old habits. She was wearing that wig because that’s how she was dressed up to film her new video for Womanizer.
She probably didn’t had time to change her outfit and appearance after finishing film the scene. Or this was made on purpose to gain some media attention.
I think Britney’s new album Circus which will come out on December 2nd is the most expected music album of the year.
