Red-Carpet Rumble: The 7 All-Time Biggest Celebrity Feuds

This week, The X Factor started here on TV in the UK, and its judges have been doing the publicity rounds. I happened to catch Sharon Osbourne on the radio discussing her daughter Kelly's fallout with Lady Gaga…According to Sharon, it all started over a frock! Supposedly Kelly said she wasn't impressed with Gaga's dress on her E! TV show, Fashion Police, and then all of Gaga's little monsters got a bit, well, monster-like by harassing Kelly on social media. Sharon said she had then contacted Gaga's people and asked them to put a word out to make it stop, but instead it all blew up, with Gaga writing an open letter to Kelly - and then Sharon writing a reply.This made me think of all the celeb mash-ups that we have heard about over the years and how they have entertained us. Yes yes, the world would be a better place if there weren't any celebrity feuds, but wouldn't it be just a teensy bit dull?
