These lads are no strangers to a spot of controversy - from Twitter feuds to naked photos - check out the 8 bad boys of pop.
Justin's no stranger to the bad boy life - he's been involved in multiple run ins with the paps, including this incident where Biebs launched a water bottle at some waiting snappers in Miami. Picture: Splash
Louis and Zayn were embroiled in some controversy this summer when the pair were caught on camera talking about illegal substances in the back of a car. Tut tut! Picture: Instagram
Eminem hit the headlines recently for his offensive lyrics involving Iggy Azalea and Lana Del Rey, and he's previously attacked Britney Spears and Christina Aguilera in his songs. Play nice, Marshall!
Example has a pretty extensive track record for getting into Twitter feuds with other celebs and, apparently, the entire town of Wigan when he tweeted asking if there were "any nice people in Wigan". Awk.
Kanye West went down in history for the ultimate bad boy moment when he took the microphone from Taylor Swift as she accepted an MTV VMA award for the 'Best Female Video' and told the crowd that Beyonce would have deserved it more. Yikes!
Calum pretty much broke the internet when a leaked Snapchat of him naked hit the web. Proving that he is pretty badass, rather than deny that the photo was of him, Calum owned it and admitted the saucy snap was his. Picture: Instagram
As if THAT twerking performance with Miley Cyrus at the MTV VMAs wasn't shocking enough, Robin got caught out getting a bit handsy with a mystery blonde as they posed for a photo together - and he had a big old grope of her bum. Bet his (now ex) wife didn't see the funny side! Picture: Instagram
Pro Green is currently serving a one year driving ban for drink driving after he was caught behind the wheel over the limit. Pro had jumped in the car to chase a robber who stole his £40,000 Rolex watch on his doorstep. Picture: Twitter
