"La Apuesta" (The Bet) is a Latin pop song recorded by Mexican recording artist Thalía featuring Erik Rubin and included in Thalía’s eleventh studio album Habítame Siempre as well as the 2013 live album Viva Tour. The song was written by Beatríz Herraiz and produced by Armando Ávila. It was released on October 22, 2013 as the first single off the live album VIVA Tour. The single is a live version of the song recorded at the National Auditorium on April 26, 2013.

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. Thalía has also described it as a ‘nostalgic song’ that brings her many memories from her teen years. Thalia had written in the booklet of Habitame Siempre the following words about the song : "Nostalgia, magia, complicidad, hermandad. Y que el mundo gire y gire!" ("Nostalgy, magic, complicity, brotherhood. And may the world go round and round!"). The track is produced by Armando Ávila.

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. It shows the two artists performing the song live and it is an excerpt from their performance at the National Auditorium on April 26, 2013 which was recorded in front of an audience consisting of more than 10,000 people.
