"DFMU" (initialism for DonâÂÂt Fuck Me Up) is a song by English singer-songwriter Ella Mai. It was released on 28 January 2022 through 10 Summers and Interscope Records from her second studio album, Heart on My Sleeve (2022). It was produced by Mustard and co-produced by J. Holt.
Following the release of the single "Not Another Love Song" (2020), Mai took a hiatus from recording and public life. In October 2021, the singer revealed on her social media accounts that she had returned to the recording studio. The song was written in 2020 during a writing session with Mustard. In an interview with Apple Music 1 Mai explaining the meaning and writing process of the song:<blockquote>"It was almost a therapy session when I was in the session. But I think thatâÂÂs the best way. All the people that I grew up listening to are always very, very honest. And IâÂÂve always just appreciated honesty. I think itâÂÂs the best way I think that people can relate to you also so. [...] I was having a very honest conversation with Prince Charlez who I wrote the song with about I was going through at that point. And it just was basically a conversation, and it just came together that way. And I think those are the best songs because storytelling is just conversation really. It was one of the ones during the recording process that I just knew it had to make"</blockquote>
Mai performed a medley of "DFMU" and "Leave You Alone" at The Tonight Show Starring Jimmy Fallon in May 2022.
The music video for the song, directed by Loris Russier, was released on 2 February 2022 through the singer's YouTube channel.
