Cymphonique And Kat Beef?

Another one? Guys why?? Anyways, sources say that a beef is brewing between Cymphonique and Kat. For those who don't know, Cymphonique is already in a foursome beef with Solo and Karmin and now it seems to be Kat. This started after the two were at a signing yesterday, they both were there signing with each other because they are friends and they were supporting the "Give Back Foundation" which is the charity they both own. The details still aren't too clear right now, but for some reason the two got into an argument and Cymphonique was heard saying "I paid you what I owe you what the hell are you talking about?" Kat screamed "What you think I'm fucking stupid?" Kat said "Nah nah don't get loud bitch!" Then its said that they had a fight. Like i said the details are really not clear and we aren't sure if this actually happened. But multiple sources say that this did in fact happen, and its said to have been captured on a security camera, but wasn't released to the media yet. So is Kat and Cymphonique beefing? Maybe, maybe not. We'll dig and let you know....
