Britney Spears is once again at the center of a viral controversy after reports claimed the pop icon caused a bizarre scene at a Los Angeles restaurant. Witnesses allege Britney barked, yelled, smoked indoors and walked around with a knife before security escorted her home. The incident comes just weeks after her rehab stay and DUI case. Britney’s team has now fired back, calling the story “blown out of proportion” as social media explodes with concern over the singer’s wellbeing.
