Christina and Lady Gaga, Cheryl Cole and Lily Allen, Elton John and Madonna. We take a look at famous celebrity feuds.
Celebrity feuds are nothing new, but whilst some are of a personal, serious nature, and deep-rooted in the past (Angelina Jolie and her father, Oscar winner Jon Voight), some are rather more volatile.
Some stars seem to like a good fight. Eminem, Lily Allen, Courtney Love, Lindsay Lohan and Paris Hilton have had wars of words with many fellow celebrities.
Whether the fights are sparked by jealousy (Allen and Love fought over a Chanel dress), broken hearts and exes (Mariah Carey and Eminem, Kate Moss and Jade Jagger, Paris Hilton and Mary-Kate Olsen), work strain (allegedly Simon Cowell and Ellen DeGeneres, Sarah Jessica Parker and Kim Catrall) or personality differences (Girls Aloud and Nadine Coyle, Liam and Noel Gallagher) they always make the news and for many, are very entertaining.
On a positive note, stars tend to kiss and make-up eventually (Paris Hilton and Nicole Ritchie are friends again), but for some, it's war till the end (Sharon Osbourne still won't stop talking about her dislike of Dannii Minogue despite the fact that the two haven't worked together in a long time).
Take a look at our gallery to see what celebrities have had a run in with each other.
