Celebrity Insults

Lily Allen and Cheryl Cole have hit the headlines for all the wrong reasons. After the Girls Aloud singer cruelled labelled Lily "a chick with a d***", devastated Lily hit back with a diary entry on her website: Cheryl, if you're reading this, I may not be as pretty as you but at least I write and sing my own songs...Taking your clothes off, doing sexy dancing and marrying a rich footballer must be very gratifying. Your mother must be so proud, stupid b****."

Ouch, that's her told. Or is it? This isn't outspoken Cheryl's first row. When '90s girl group All Saints made a comeback recently, Cheryl kicked things off by saying, "The new All Saints sound just sounds just like us. They must have looked at what's working at the moment and thought we'll go that way." All Saints soon struck back, with Shaznay Lewis putting it bluntly: "In all honesty they are stupid little girls and we don't really give a f***".

Back biting and cat calling are all part of celebrity life - but there is no need for some of the harsh put-downs we have uncovered in the gallery below.
