Nicki Minaj & Mariah Carey: Nicki and Mariah have become famous as feuding judges on American Idol. A source told US gossip site TMZ, "These girls just don't like each other."
Jake Bugg & One Direction: Jake Bugg has made no secret of his distaste for X Factor boyband One Direction. Bugg told Shortlist magazine, "People [call them the new Beatles] because they broke America, but that don't mean a thing. I mean, [One Direction] must know that they're terrible."
Azealia Banks & Rita Ora: Originally, a photo like this wouldn't have been so unrealistic, as the two planned to work together. However, a source recently told The Sun that Azealia called Rita a 'thirsty wh**e' and Azealia went on a Twitter rant against Rita, saying, "She's mad she's Rihanna's understudy."
Elton John & Madonna: There is no chance that we'll ever see this pair team up. According to The Sun, Elton laid into Madonna, saying, "Why is she such a nightmare? Sorry, her career is over. Her tour has been a disaster and it couldn't happen to a bigger c***." He also accused her of looking like a "fairground stripper."
Liam & Noel Gallagher: This photo's actually real, but don't plan on seeing it happen again anytime soon. After Oasis split in 2009, Liam and Noel have taken it in turns to make digs at each other via any means necessary (other than actually speaking). Speaking recently to Time Out Dubai about a possible reunion, Noel said, "I wish people would give it up - it's not going to happen, for no other reason than we've moved on."
Crystal Castles & Katy Perry: While we can't deny that this photo is something we'd like to see, this is another that isn't going to happen. Katy hasn't spoken out about Crystal Castles, but singer Alice Glass slammed her in an interview with NME, saying, "Like f**king Katy Perry spraying people with her f**king d**k, her f**king c** gun c**ming on f**king children." She added, "It's f**king evil. Don't prey on vulnerable people like that. Don't encourage little girls to get dressed up, to have cupcakes on their t**s to get people to lick them off, 'cos that's what you're insinuating."
The Voice & The X Factor: We're not even sure if all the judges would fit on one stage, but we'd like to see them try. However, Danny O'Donoghue and Will.i.am recently said they don't even know who James Arthur is, while in The Sun, Jessie J hit out at The X Factor for 'ridicule' and 'bullying' entrants.
Matt Cardle & James Arthur: It's probably a good thing that this isn't going to happen. After James Arthur's win, Matt Cardle told The Sun, "I said, 'Look, James, you're very talented but you haven't sold two million records yet, which I have. You haven't had two top ten albums yet, which I've had. Don't start mouthing off before you've even really left the show.'" James Arthur responded, "2 million returned and now live in the bargain bin at asda give it up the tunes are brutal.. the desperation for press is embarrassing."
Madonna & Lady Gaga: To be fair, it's more of a feud between fanbases, but that certainly doesn't mean these two superstars are on good terms. When asked about similarities between her hit 'Express Yourself' and Lady Gaga's song 'Born This Way', Madonna said: "I thought, 'What a wonderful way to redo my song'. I mean, I recognised the chord changes. I thought it was... interesting."
Chris Brown & Frank Ocean: We can't imagine these two ever reconciling and we wouldn't want them to, either. Brown apparently threatened to 'beat the living s**t' out of Ocean when the two had an altercation over a parking space. Let's keep them away from each other, please.
