The Black Keys vs. Nickelback: At the start of 2012, The Black Keys blamed the death of rock and roll on the likes of Nickelback, and the people who had allowed them to become one of the biggest rock bands in the world. Nickelback then 'thanked' The Black Keys for calling them the biggest band in the world, and recently The Black Keys 'apologised' to Nickelback for the comments. "There's much worse bands than Nickelback. Maybe," said Patrick Carney of the band, "I don't like bad music, but look, I've got a lot of friends and not one of them has a Nickelback record."
Elton John vs Madonna: The two queens of pop went to war at the 2012 Golden Globes awards. "Madonna doesn't have a f**cking chance" said Elton of Madonna's nomination for the Best Song award - which she then went on to win, much to Elton's obvious disgust. "He's known to get mad at me," Madonna later revealed. "He'll win another award. I don't feel bad."
Tupac vs. The Notorious B.I.G: Once friends, the relationship between the two rappers turned sour when Tupac was shot five times and robbed of $40,000 in 1994. Surviving the attack, Tupac recorded a series of songs alleging that his former friend had known about the set-up but had chosen not to warn him. With tensions boiling between the east and west coast hip hop communities and diss tracks flying between the two rappers, the feud reached its bloody climax in 1996, with Tupac gunned down in a drive-by shooting and Biggie suffering the same fate some six months later.
Noel Gallagher vs. Liam Gallagher: At each other%u2019s throats for years, the feud between the two brothers eventually spilled into the courts in 2011. It was Liam who cast the first stone, suing Noel for alleging that Oasis had cancelled their 2009 headline slot at V Festival because Liam was hungover. Noel then retracted the statement, citing Liam's laryngitis as the actual reason, but responding with a counter-libel case accusing his brother of leaving abusive voicemail messages on his wife's phone and attacking him with a guitar.
Billy Corgan vs. Courtney Love: The pair have a long history as friends, ex-lovers and two of alternative rock's biggest stars, but when Courtney included songs they'd written together on the 2010 Hole album 'Nobody's Daughter,' Corgan told the Rolling Stone: "I haven't given my permission. I have no interest in supporting her in any way, shape or form." Courtney apologised, calling Corgan: "A king, a prince, and my beautiful noble boy," but Corgan later took to Twitter to say: "Only u could abandon such a beautiful, incredible child who is smarter than u, cooler than u and better than u. Oops, did I say too much?"
Bono vs. Chris Martin: Appearing on BBC's Radio 1 in 2010, the U2 front man began a train of thought about Chris Martin's songwriting being on a par with Paul McCartney before sending it crashing into far more alarming territory. I think he's that good a melodist, he said. I mean, he's a w*nker... he's a completely dysfunctional character and a cretin but he happens to be a genius melodist. He then sheepishly added that he was joking entirely as Joe Wiley desperately tried to salvage her radio show.
Lily Allen vs. Katy Perry: When Katy Perry described herself as the "fatter version of Amy Winehouse and the skinnier version of Lily Allen, it was inevitable that the outspoken singer would have something to say about it. Lily's initial response was to threaten that she would post Katy Perry's phone number on Facebook. Branding the American singer as "crass," she then said: "You're not English and you don't write your own songs, shut up!"
Miley Cyrus vs. Radiohead: Few would've had Miley Cyrus down as Radiohead fan, but when the teenage pop star was apparently snubbed by her "favourite" band after inviting them backstage at the Grammy's, she told a radio DJ: "I left 'cause I was so upset. I wasn't going to watch. Stinkin' Radiohead! I'm gonna ruin them, I'm going to tell everyone." The band's publicist then responded with the statement: "When Miley grows up, she'll learn not to have such a sense of entitlement." Meanwhile, Thom Yorke wondered what he'd done wrong.
Morrissey vs. Robert Smith: When a magazine posed Morrissey with the hypothetical dilemma of choosing between shooting The Cure frontman and The Fall's Mark E. Smith, the ex-Smiths singer's response was: "I'd line them up so that one bullet penetrated both simultaneously, before adding: "Robert Smith is a whingebag. I expect he's quite supportive of what we do, but I've never liked The Cure." Incensed by these comments, Smith said: "If Morrissey says not to eat meat, then I'm going to eat meat; that's how much I hate Morrissey."
Jay-Z vs. Nas: Another spat from the vaults of hip hop's more high-profile feuds this one raged for years, with the two rappers trading all sorts of insults through various verses. Jay-Z boasted of sleeping with the mother of Nas' child, called him a fake and branded him a one-hit wonder in reference to the success of his 1994 Illmatic album. Nas response was Ether; a four-and-a-half minute diss track that asked: You seem to be only concerned with dissing women, were you abused as a child, scared to smile, they called you ugly?
M.I.A vs. Lady Gaga: Can you call it a feud if one of the parties remains tight-lipped throughout? In 2010, M.I.A joked about the garish product placement in Lady Gaga's 'Telephone' video (Dude, she even plugs a burger!) before describing the singer as a mimic. She models herself on Grace Jones and Madonna, but the music sounds like 20-year-old Ibiza music, she told the NME. Shes not progressive, but shes a good mimic. She sounds more like me than I f*cking do! Gaga wisely choose not to rise to the bait.
Axl Rose vs. The Offspring: Nearly a decade in the making, Guns N' Roses almost lost the tentative title to their heavily-delayed Chinese Democracy album, thanks to an April Fool's Day prank pulled by The Offspring. "You snooze you lose," was the explanation from the Offspring singer, Dexter Holland. "Axl ripped off my braids, so I ripped off his album title," he said in a statement annoucing that The Offspring would be using the name for their fifth album. After dropping the prank, Holland later told Spinner magazine: "I heard Axl was looking into legal options but there aren't any, since you can't copyright an album title before it's released."
