The First Lady Michelle Obama is definitely noted for her style and fashion sense. And yesterday on her 49th birthday, she rocked a nice new haircut, also just in time for her husband's second inauguration. Apparently there was no announcement made but her office tweeted the picture from her new Twitter handle, @FLOTUS. This actually replaces her old handle, @MichelleObama. And of course, you will know if the First Lady is tweeting because he tweets will be signed -mo. Check out her new hair. What do you think about it?
