In the same year, Coca-Cola wanted Selena to become one of their spokespeople in Texas. The jingle used in her first two commercials for the company was composed by A.B. and Chris Pérez—the latter of whom had joined Selena y Los Dinos several months earlier as the band's new guitarist. Pérez began having romantic feelings for Selena, despite having a girlfriend in San Antonio. After a trip down to Mexico with the band, Pérez thought it would be best for them both to distance himself from her, but he found that impossible and chose to try to build a relationship with her. They expressed their feelings for each other at a Pizza Hut restaurant and shortly afterward became a couple. Pérez and Selena hid their relationship, fearing Quintanilla, Jr. would try to break it up.
