36-year-old Britney Spears still has it. The singer has been in the industry for years, starting with her days in The Mickey Mouse Club. She starred alongside Christina Aguilera, Justin Timberlake, Keri Russell, Ryan Gosling and JC Chasez before moving on to build a solo singing career. Over the last two decades, Spears has topped the charts and toured the world. In fact, Spears is on tour right now, and at a stop in Maryland, she suffered a slight wardrobe malfunction. 

In a video captured by YouTube user Salvatore Bellamo, Spears has a nip-slip at The Theater concert venue inside MGM National Harbor in Maryland. Dressed in a stunning black outfit that showed off her curvaceous body, Spears sang “Do Something” as her nipple jumped out of her bra. The wardrobe malfunction occurred after she jumped out of a cage. She continued on to perform for two minutes without any one of her dancers noticing. The fact that six dancers who were constantly grabbing and holding her don't notice, or choose not to speak up, about the nip-slip is odd. Spears is no stranger to wardrobe malfunctions though, and has experience with nip-slips. Check out the video below, and watch for the slip at around 4:38.
