Chris and Kem are Love Island stars Chris Hughes and Kem Cetinay. Following on from a live rap collaboration with Stormzy on stage at the 2017 V Festival, the reality TV duo made their recording debut with this cut, which makes evident their love of grime.
The song was produced by Z Dot who has also worked on tracks for the likes of Stormzy, Wiley and Professor Green.
One person who isn't so thrilled about Chris and Kem's attempts at starting a rap career is grime legend Lethal Bizzle, who accused the pair of stealing his catchphrase.
He told Chris and Kem they "need to have a conversation" after he said they used his phrase 'Leave it', without permission. In 2011 Lethal released a track called "Leave It Yeah," which has since become one of his well-known phrases. He commented:
"I wasn't even bothered about it to be honest with you, it's the people that made me realise like, 'Rah, Bizz, are you getting a percentage out of this?'
I don't need the money but the principle is you're taking the piss, and you're not even crediting [me]... You're using it like you lot made it popular."
Lethal added later on Twitter that he was asked by the label to feature on the song and turned it down - but "didn't know or hear" about the "leave it" lyric.
The Flaming Lips' "Do You Realize??" was named in March 2009 the official Rock Song of Oklahoma. Four years later, Oklahoma's governor Mary Fallin pulled the tune as the state's official rock song in a move her office said had more to do with priorities than musical taste.
