Christopher Gilbert Pérez is an American guitarist, best known as lead guitarist for the Tejano band Selena y Los Dinos. He married the frontwoman of the group, Selena, on April 2, 1992. Pérez grew up in San Antonio, Texas as one of two children of Gilbert Pérez and Carmen Medina. In 1986, he began his tenure by joining Shelly Lares' band. By the late 1980s, Pérez was respected among Tejano musicians for his guitar skills. This caught A.B. Quintanilla's attention; at the time, A.B. was seeking another guitarist for the band he produced, Selena y Los Dinos. Between one and two years after Pérez joined the band, he and Selena began a personal relationship.

Selena y Los Dinos was an American Tejano band formed in 1981 by Tejano singer Selena and her father Abraham Quintanilla. The band remained together until the murder of Selena in 1995, which caused the dissolution of the band in the same year. When Selena was signed with EMI Latin, EMI president José Behar told Selena that "the world wanted Selena, not Selena y Los Dinos." Selena then began releasing her solo studio albums under her name and her own logo title Selena instead of Selena y Los Dinos. Before Selena was signed with EMI, the band had sold more than 80,000 copies in the state of Texas.
