a collaboration in December 2018. They began teasing the project on social media in June 2019, with each sharing a 20-second video teaser. They uploaded teasers of the song's music video to their social media accounts on June 19, 2019. The former confirmed it as a single later that day along with its release date and artwork. Live performances Mendes and Cabello performed the single at the 2019 MTV Video Music Awards on August 26, 2019. On September 5, 2019, Cabello performed an acoustic version of the song on Elles Women in Music Party presented by Spotify in The Shed On September 6, during the Shawn Mendes: The Tour live show in Rogers Centre, Toronto, Mendes and Cabello performed "Señorita".

Mendes has added the single to his setlist on his ongoing tour, as a medley with "I Know What You Did Last Summer"—which Cabello also features in—and "Mutual". Critical reception Shaad D'Souza from The Fader praised the single for being effortlessly steamy and wonderfully lightweight, concluding that although Cabello is clear MVP, the song would fizzle without Mendes as her foil. TJ Lovell from Medium called the track a sexy ode to a vacation rendezvous that allows the pair to flex their undeniable chemistry on and off the mic. Lovell ended by giving the song 4 out of 5 stars, and called it a fun if unremarkable track that'll sound right at home in Mendes' and Cabello's discographies. Commercial performance "Señorita" debuted at number two on the Billboard Hot 100 on July 6, 2019. It later peaked at number one on the chart issue dated August 31, 2019 dethroning Billie Eilish's "Bad Guy", becoming Mendes' first US number-one song and Cabello's second after "Havana". Cabello became the youngest female artist to achieve a second Hot 100 number one and a fourth Mainstream Top 40 chart-topper since Rihanna (2010). It was replaced by Lizzo's "Truth Hurts" the following week. The single was the most-streamed song on Spotify in 2019 and 9th overall.
