The song was first developed when Lopez was talking to Martin, Kotecha and Cory Rooney about relationships during a break from the album recording.

The black-and-white music video features British model David Gandy and Lopez during love scenes in a desert.

Lopez promoted the track with live performances on the 2014 Billboard Music Awards, American Idol, Late Night with Jimmy Fallon, as well as on her concerts throughout 2014 - blending the song with elements of "Ain't No Mountain High Enough" as well as a dance-break.

[8] While taking a break in between recording sessions for A.K.A., Lopez had a discussion with Cory Rooney, Max Martin, and Savan Kotecha about relationships.

Serban Ghenea mixed the song at MixStar Studios, Virginia Beach, and John Hanes engineered the track.

[23] For Andy Walsh of Renowned for Sound, the song "deal[s] with the stars romantic past and the often-confusing side of relationships.

"[24] Caroline Sullivan of The Guardian noted that the track "sweetly extols the pleasure of finding the right person long past the first flush of youth.

Amaya Mendizabal of Billboard enjoyed its "fun and free feel," praising Max Martin for "liv[ing] up to his legacy, creating a sound reminiscent of past summertime hits," also noting that it "evokes a nostalgic air that will resonate with true J.Lo fans.

"[27] Writing for Fuse TV, Jeff Benjamin praised the singer for "successfully straddl[ing] the line between pop and hip-hop on this song, as she always does.

"[13] Mike Wass of Idolator agreed, calling it "an adorable pure-pop explosion that expertly straddles the divide between J.Lo's urban roots and much-loved dance moments."

Wass also praised its lyrical content, calling it "a surprisingly mature theme" and named it "a hugely enjoyable bubblegum pop song.

"[28] Jazz Tangcay of SoSoGay called it "a pop-centric song and catchy on the first listen,"[29] while Lydia Jenkin of The New Zealand Herald noted that the track "has the kind of lively spirit and hummability that's made J-Lo a household name in the past, and seems an effortless throwaway hit.

"[21] Amy Davidson from Digital Spy agreed, writing that its lyrics are so convincent that it "redeems the crowded jumble we heard on 'I Luh Ya Papi'."

Davidson praised the track, calling it "seductive pop that sits on the right side of J-Lo's hip hop influences.

"[37] In contrast to the positive response, Alexa Camp of Slant Magazine called it "forgettable", writing that the fact that the song gets the full single treatment suggests that Lopez probably shouldn't add A&R exec to her extensive résumé anytime soon.

The conditions to shoot in were very challenging due to the weather - we were in the desert outside LA and the winds were incredibly strong and we had to deal with plummeting temperatures and sandstorms - but the atmosphere on set was great and we all had a lot of fun."

A music video for the song was shot in the California desert outside of Los Angeles in early May, with Anthony Mandler being the director.

"[1]On May 27, 2014, Lopez teased the video on her Instagram account, uploading a sneak peek of it, also announcing that it would be fully released the same day on Entertainment Tonight.

"[50] The black-and-white music video starts with Lopez exclaiming, "I knew I had to leave the world behind me to find out who I was," as she wanders the Californian desert in "her finest couture gown," as noted by Mike Wass from Idolator.

Mike Wass of Idolator called it her "sexiest visual since 2011's breathtaking 'I'm Into You', also noting that "it's a fairly simple set-up but, in director Anthony Mandler's capable hands, it turns out to be an absolute feast for the eyes.

"[50] Lucas Villa of AXS found the video to be reminiscent of late director Herb Ritts' classic clips.

'[56] Michelle McGahan of Pop Crush praised Lopez for "not only look[ing] jaw-dropping in a one-shoulder, sparkly black dress, but she belted out the tune with such fervor and showed the world just how well she can really move.

[58] Lopez also performed the track during the finale of the thirteenth season of the American Idol, wearing a unique blue one-piece.

[59] Halfway through "First Love," Jennifer shouted that she was ready to dance — and started to run off the stage and jumped onto the judge's table where she showed some sexy moves.

Backed by a large group of dancers, Lopez returned to the stage for a quick dance break before reminding everyone, "I'm still Jenny from the Block!".

[59] The song was also part of Lopez's setlist during her concerts in 2014, including the "Powerhouse 2014" and the "iHeartRadio Ultimate Pool Party", on June 28, 2014.
