Rap's ugliest feud: The real story behind Kendrick Lamar and Drake's decade-long beef and the 'paedophile' lawsuit that led to THAT explosive Super Bowl 'diss'

Drake and Kendrick Lamar's 13-year feud was brought to the forefront of public awareness on Sunday night when the Not Like Us rapper performed his diss track during the Super Bowl halftime show. During his performance - which was dubbed the 'worst halftime show ever' - he teased the controversial track throughout, before performing a redacted version. Not Like Us was released on YouTube with what appeared to be a graphic of Drake's mansion with sex offender symbols, as he accused the musician of being a 'certified pedophile' over his alleged interactions with younger women. Drake has responded to the claims by bringing a legal action.

In addition to performing the song - which he is currently being sued for because it includes lyrics labelling Drake, 38, a 'certified pedophile' - Kendrick brought out Serena Williams, who is also in a feud with the Canadian rapper. Kendrick opted not to say pedophile so as not to trigger another lawsuit, telling the crowd, 'I want to perform their favorite song, but you know they love to sue.'. He did, however, go on to deliver two other controversial lines, including 'Say Drake, I hear you like them young' and 'trying to strike a chord and it's probably a minor,' as the crowd sang along.

Drake and Kendrick Lamar 's 13-year feud was brought to the forefront of public awareness on Sunday night when the Not Like Us rapper performed his diss track during the Super Bowl halftime show. During Drake's Club Paradise Concert he brought out Kendrick in 2013 when they were on good terms alongside other rappers including ASAP Rocky and Chasin Cash. In addition to performing the song - which he is currently being sued for because it includes lyrics labelling Drake, 38, a 'certified pedophile' - Kendrick brought out Serena Williams (pictured), who is also in a feud with the Canadian rapper.

Drake said in a statement issued via lawyers prior to the song playing in the half-time show of this year's Super Bowl: 'UMG is masquerading as a champion of artistic freedom by calling its actions merely 'entertainment,' but there is nothing entertaining about pedophilia or child abuse in the real world. 'We are confident that the evidence we will ultimately present at trial—including information we've already learned and continue to receive since filing the lawsuit—will expose UMG's gross prioritization of its own corporate profits and executive bonuses over its exclusively signed artists' well-being and the truth.'.

So as Kendrick takes their feud to a global stage and their war of words hits the courts, MailOnline takes a look back at their long-running feud... While there is clearly no love lost between the duo, the Canadian and the Compton native started out amicably, collaborating on Drake's 2011 album Take Care, Kendrick's 2012 track Poetic Justice, and ASAP Rocky's 2013 track F***in' Problems. They even happily toured together in 2012 during Drake's $42.6 million, 65-date Club Paradise Tour.

Things began to change in 2013, with the release of Big Sean's song Control because it featured a guest verse by Kendrick that made it clear he thought he was better than his contemporaries. 'I'm usually homeboys with the same n****s I'm rhyming with / But this is hip-hop and them n****s should know what time it is / And that goes for Jermaine Cole, Big K.R.I.T., Wale, Pusha T, Meek Millz, ASAP Rocky, Drake,' Kendrick rapped, placing himself at the top of the hip-hop food chain.

'Big Sean, Jay Electron', Tyler, Mac Miller / I got love for you all, but I'm tryna murder you n****s / Tryna make sure your core fans never heard of you n****s / They don't wanna hear not one more noun or verb from you n****s.'. While there is clearly no love lost between the duo, the Canadian and the Compton native started out amicably, collaborating on Drake's 2011 album Take Care, Kendrick's 2012 track Poetic Justice, and ASAP Rocky's 2013 track F***in' Problems.

Drake addressed the verse on multiple occasions, with the Canadian singer questioning the longevity of Kendrick's career as well as the impact of his music as a direct response to Control. For instance, he told Pitchfork: '[Kendrick is] giving people moments. But are you listening to it now, at this point in time?'. 'Okay... It was real cool for a couple weeks [but] if I asked you, for example, how does that verse start?'.

Drake commented on being name-checked by Kendrick on Control in an interview with Billboard, saying 'it just sounded like an ambitious thought to me'. He continued: 'I know good and well that Kendrick's not murdering me, at all, in any platform. So when that day presents itself, I guess we can revisit the topic.'. It appears that the feud between them was also in part due to their differing attitudes towards wealth and fame, with Kendrick being fiercely tight-lipped about his private life while Drake is known for showing off his lavish lifestyle on Instagram.
