WELL.. That didn't take long. Niki Manaj started swearing at Mariah Carey and threatened to KNOCK HER OUT in Charlotte. It's hard to understand and the video isn't all that great...but good enough to see how uncomfortable Keith Urban is sitting between them. Thinking "they are getting like 5 times what I'm getting paid...they aren't paying me enough to sit here!"  You can also hear Randy Jackson in the background trying to calm things down....Where was Seacrest?
