Lopez first performed "First Love" during the 2014 Billboard Music Awards, where she was awarded with the 2014 Icon Award. During the performance, Lopez blended "First Love" with Motown classic 'Ain't No Mountain High Enough.' 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. (We're talking, rivaling Beyoncé. That's how good her performance was!) The singer looked so fierce and she so totally nailed the number." She also performed the same medley during her free concert in the Bronx, on June 4, 2014. Lopez also performed the track during the finale of the thirteenth season of the American Idol, wearing a unique blue one-piece. 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!". 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.
