Premise
The clip sees Gomez lying on a couch spliced with scenes of her and Bad Bunny at a bar. Casper Smart, playing an old rich man, enters the place and is attracted to Gomez. He takes her to his house as Bad Bunny raps his verses at the bar. These scenes are also cut with the singers performing on the roof of the Hotel Rosslyn Annex at night. Gomez seduces Smart and handcuffs him to the bed. She plays with his watch before getting off the bed and leaving with a bag full of money. Bad Bunny appears to be waiting for her, and they kiss before getting in the car. The video ends as the duo is about to drive off.
Live performances
Due to the song becoming a huge success, Gomez was invited to perform it at several radio stations and during interviews. She sang the song regular and acoustic at iHeart Radio Mi Música. She also sang it in Spain in La Vida Moderna and Sale el Sol in acoustic, and regular on Operación Triunfo. Her performance on the latter garnered some attention due to a change in the lyrics at the request of the producers due to them thinking they were "too sexual". Although Gomez agreed, she later stated it bothered her and said she accepted "out of respect" and because it was "a great opportunity", but believes that it wouldn't be done to a man, listing Ozuna and Enrique Iglesias as examples. Gomez performed the song with Bad Bunny at the Latin American Music Awards of 2017, which she also hosted; the performance was later uploaded to YouTube and has garnered over 50 million views. The song was included on her setlist as an opening act for Fifth Harmony's 2017 PSA Tour and on her own tour in 2018. She sang the song last in her performance at Viña del Mar on March 2, 2019. Gomez included "Mayores" in three medleys: the first at the 2019 Latin American Music Awards together with "Sin Pijama" and "Mala Santa", before receiving the Extraordinary Evolution Award from Pitbull. The second time was at the 2019 MTV Europe Music Awards, this time with "24/7", a track from her debut album replacing "Mala Santa". The third time was at the LOS40 Music Awards 2019 with "Mala Santa" being brought back. All three performances had different arrangements. In the latter performance Gomez rewrote Bad Bunny's verse with lyrics from her "side of the relationship" and some added lyrics, including a reference to her feature in the "Dura " with Daddy Yankee, Natti Natasha, and the rapper.
