It was sent for radio airplay in France on 11 March 2021 as the sixth and final single from Future Nostalgia before being released for digital download and streaming on 4 June globally.

The song samples "My Woman" by Al Bowlly with Lew Stone and His Monseigneur Band, using it for several aspects, thus Bing Crosby, Max Wartell and Irving Wallman are also credited as writers.

The lyrics explore themes of heartbreak and personal growth, seeing Lipa falling in love again with a new lover following a rough split.

The song has been certified gold in the United Kingdom by the British Phonographic Industry (BPI), platinum in Austria, Italy, Portugal and Spain and multi-platinum in France, Brazil, Poland and Canada.

The visual sees Lipa and her rodeo clown-styled dancers in the hotel's ballroom line dancing, riding mechanical bulls that sometimes disappear and painting eggs.

Lipa performed the song on multiple occasions in 2021, including at the Time 100 event, at the 41st Brit Awards as part of a Future Nostalgia Medley and at the iHeartRadio Music Festival.

"Love Again" was written by Lipa and her longtime collaborators Clarence Coffee Jr., Chelcee Grimes and Stephen Kozmeniuk, the latter of whom also handled the production.

With her album Future Nostalgia, Lipa wanted to create "old-styled" music with a modern twist, being inspired by artists that she grew up listening to.

[3] Following the session, Kozmeniuk was reading a Studio 54 book and he was picturing the work of Donna Summer where she had built up with a lot of a drums and string parts in an intro, before the song began.

Mixing was handled by Matty Green at Studio 55 in Los Angeles while Chris Gehringer mastered the song at Sterling Sound in Edgewater, New Jersey.

[14] The song's melodramatic 21st-century nu-disco production matches its lyrics,[15][16] and includes gloopy violins,[17] orchestral sounds[9][12] as well as disco beats and synths.

[12][26][27] Lipa uses her lower register husky vocals that encapsulate an undeniable sense of urgency, as if she is mimicking the rush of falling in love with hints of tension ever so often.

[38] It is a 1980s-styled, percussion and synth-heavy[39][40] remix that introduces simple melodies, funk-laced instrumentals and strutting beats with a retro charm; although, the "My Woman" sample is no longer heard.

[53][54] Elly Watson of DIY praised the use of the "My Woman" sample as "goosebump-inducing,"[55] while MusicOMH's Nick Smith stated it has a "slapping effect."

"[59] In a separate, negative review from the same publication, Nick Malone stated that the hook doesn't "pop" the way it needs to, Lipa's vocals are "non-committal" and the "My Woman" sample does not make it "soar".

[26] Writing for Stereogum, Chris DeVille found the song to be reminiscent of Vicki Sue Robinson's "Turn the Beat Around" (1976),[60] while Jeffrey Davies' review for Spectrum Culture saw him compare it to "I Feel Love" (1977) by Donna Summer.

"[27] Slant Magazine ranked "Love Again" as 2020's 25th best song and writer Sal Cinquemani praised it for demonstrating "Lipa's knack for wringing pathos from everyday dating woes and pouring it into sublime dance-pop."

[17] From her review in Billboard, Bianca Gracie saw that the use of strings adds a "jolt of nostalgia", while the lyrics see Lipa in an "out-of-body love experience".

[21] In April 2020, Christopher Rosa of Glamour ranked it as Lipa's sixth best song, viewing it as the album's most "overtly disco" track and "grandiose ode to falling in love against your better wishes".

He also wanted to illustrate the song's romantic message, like the idea of a love coming up again that seems like a once in a lifetime experience that is pure, intense and unexpected, which he compared to "like these delicate flowers or animals that are just designed to blossom and intercourse just once and then they die" as well as the "tense connection between the humans and their recovered feelings".

[101] The visual was filmed at the Grosvenor House Hotel in London about three weeks before its release, during rehearsals for Lipa's performance at the 41st Brit Awards.

These shots were the hardest to shoot so the team worked with the tension of the ropes attached to the horse's neck as well as adjusting its natural shadow.

She wears Rick Owens grill kiss leather boots, camouflage green cargo pants, a longline brown cow print jacket and a cow-print bra; the latter three clothing items are from The Attico.

[118] In Refinery29, Eliza Huber said that although Western tropes in fashion have been popular for a while, Lipa makes the style "feel surprisingly fresh" in the video, while also comparing it to the clip for Madonna's "Don't Tell Me" (2000).

[61] For Grazia, Marisa Petrarca called the video "absolute gold" with Lipa embracing a "glamorous take on Western fashion" containing "epic" ensembles.

[119] The staff of Wonderland said their minds "are totally blown" with the video, while calling the fashion "gorgeous" and the choreography "a TikTok worthy dance routine".

[117] In a review from Billboard, Gil Kaufman said that Lipa gets her "urban cowgal on" in the visual and thought she took a "sensual, slow-mo ride" on the mechanical bull.

[120] Cinquemani thought that the main takeaway from the video was "keep falling for the wrong person and the yolk's on you" while noting its use of special effects and praising the surreality.

[122] For Consequence, Wren Graves named the video a "campy rodeo fantasy", while commending how Lipa waves her lasso, similarly to Wonder Woman.

[128] Lipa performed the soft piano rendition of the song as a duet with Elton John at his AIDS Foundation Academy Award Party on 25 April 2021.
