Rico Love came up with the song when he was working in the studio with Jim Jonsin. He told The Boombox
: "It came to me when I heard the chorus to the song. It's pretty fast the way my process is - I don't over-think; I don't sit down and come up with concepts. Usually the music kinda tells me what to say. I kinda figure out instantly what I feel like a track is gonna say. With 'Mr. Wrong,' I felt like it described myself and my relationships that I have with women. Same as [Melanie Fiona's] '4AM
' -- it's kinda autobiographical for me. I'm just describing what I've heard women in my life say to me."
