"Mi Nuevo Vicio" is a song by Mexican singer Paulina Rubio, featuring Morat, a Colombian band. It was released on 27 January 2015 by Universal Music Spain, and was later included on the track list of her eleventh studio album, Deseo (2018). The song was written by Juan Pablo Isaza, Juan Pablo Villamil, Simón Vargas, Alejandro Posada and Mauricio Rengifo, and produced by Sky Adams, Carlos Paucar and Rengifo. Musically, "Mi Nuevo Vicio" is a departure from her usual latin pop sound, and adapts to Colombian rumba with elements of rock pop. Lyrically, this talks about how genuine feelings develop during a love affair.

Morat is a Colombian Latin pop rock band formed in the country's capital city, Bogotá. The band is made up of Juan Pablo Isaza, Juan Pablo Villamil, and the brothers Simón Vargas and Martín Vargas. Drummer Alejandro Posada was also a founding member of the band, but left in 2016 and was replaced by Martín Vargas.
