It was confirmed the single to be the second single from the album in January 2007 in Mexico. Originally, in 2006, "Bésame Sin Miedo" was to be released as the second single. Instead, plans were made to release "Bésame Sin miedo" in the rest of Latin America and release "Celestial" only in Mexico. Due to the band being too busy recording RBD: La Familia, promoting both albums (Celestial and Rebels) and touring around the world, plans to release "Bésame sin miedo" were postponed. Therefore, "Celestial" was released in Mexico in March 2007 and in the rest of Latin America the song was sent to radio at the end of April.
On February 11, 2007, RBD recorded the music video for "Celestial" nearby the Popocatépetl and Iztaccíhuatl volcanos in Mexico City. The video was directed by Esteban Madrazo, who also directed former Spanish single "Ser o Parecer". The group members wear hippie outfits in the video. On February 27, the music video premiered on 'Ritmoson Latino', a Televisa music channel in Mexico.
