The music video, directed by Jessy Terrero, was filmed along with Guerra in the elementary school St. Patrick & Assumption/All Saints, in Jersey City, New Jersey. The full music video premiered on Iglesias' Vevo account on 21 May 2010. As of May 2019[update], the video has been viewed more than 620 million times on YouTube.
In the story of the video, Iglesias and Guerra are guest stars invited to sing at a school. The music video simply starts when the school principal presents them to the students and they begin to sing. The video alternates between the stage performance and three vignettes that exemplify falling in love: a student in class contrives to get his friend in trouble so he can move into his friend's seat, which is next to his crush and allows him to pass her a "Do you like me," note; an un-athletic student is pummeled at dodge ball and then rescued by a girl who likes him and has a killer throw; a straight-A student who contrives to get sent to the principal's office because he has a crush on a girl. The video has the participation of Ugly Betty actress Ana Ortiz as the principal Michelle Gomez.
The song debuted on number #22 on the BillboardHot Latin Songs, on the Tropical Songs the song debuted at number #19 and number #8 on the Latin Pop Songs. On Spain the song is charted at number #35.
