"None of My Business" is a song by English singer and songwriter Cher Lloyd, released on 19 October 2018 through Universal Music Group.

[1] The song was announced in a video posted to Lloyd's social media platforms on 16 October 2018, revealing an introduction clip and release date for the single.

[7] It incorporates "breezy production courtesy of Hitimpulse" and lyrically features Lloyd making it "very clear that she has moved on from a former flame".

[8] During the chorus she sings, "Damn, I heard that you and her been having issues/I wish you the best, I hope that she can fix you/You'll be calling me the second that it hits you, but baby, this is none of my business.

"[8] Writing for The Guardian, Kate Solomon wrote that the "sing-songy nursery rhyme feel and breezy delivery don't hide the cutting tone", and compared it to anyone who has "spent an hour scrolling through an ex's Insta feed before sending 600 screengrabs to the group chat".
