Demi Lavato Curses Out Miranda,Why? Beef? Or Disagreement?

Today, paparazzi (spying) recorded Demi Lavato fiercely lashing out at her label mate Miranda Cosgrove. She was all in her face, its difficult to make out what she was saying but we do hear the word "Bitch" a few times. Strangely enough, in the beginning Miranda was talking back, but  towards the end she just stood there with her head down getting yelled at without defending herself. The video is almost two minutes long as was released to the media where it is a very hot topic right now and its ALL over the place. Its on YouTube, the news, on other blogs and almost every other social networking site. Its blurry but you clearly see who it is and you kind of hear what Demi says especially when she raises her voice at her. Click here to check out the argument (Warning very harsh language is used) Its making people bring up the possibility of a beef, but we ant verify if its another in-house beef at the label. Some also say that it was just a disagreement and its happened before with many other artists including NiNi and her crew, so maybe, we'll dig and find out and let you guys know. *UPDATE*  Demi Lavato addressed the situation over Twitter a few hours after the story broke and this is what she said "Never meant for any of that to get out, but now that is has, I want to let the world know, I don't do music beefs or personal beefs, I'm the type of chick who tries to resolve something before it has to be called a "beef" so therefore I am not beefing with Miranda and she is not beefing with me, it was just a bad day for both sides, we have resolved the issue and kept it moving we are actually teaming up for a collab soon, which is exciting, I repeat NO BEEF! Love ya mwah!" That ends that huh? Not really though, some still are saying that because NiNi is so strict with her artists they are just trying to please her but its still some very bad blood between them two, because lets face it girls don't let things go that easy right. But for now no beef like Demi said, but if something else pops off you'll be the first to hear.......
