"La Apuesta" (The Bet) is a Latin pop song recorded originally in 2002 by the Spanish singer Rosa López in duet with Manu Tenorio for her first album.

[4] The lyrics are written by Beatríz Herraiz while the song is about a bet a guy made with his friends that he would date a certain girl, with whom he falls in love without expecting it.

Thalía stated in the documentary included on the special re-edition of the album that the song is partially true, since she really had an affair with Erik Rubin when they were members of the same pop music group (Timbiriche) back in the 80s.

The artwork of the cover of the single was revealed through the site of Amazon on October 14, 2013 and was officially confirmed by both Thalía and Erik Rubin.

[7] Some days later, it was announced that the official music video will be released on October 29, 2013 and it will most probably include the live performance of the song at the National Auditorium.
