Melody was born in Phoenix, Arizona to a Mexican mother and African American father. Her talent was first discovered at an elementary school talent show when she sang Mariah Carey's "Without You".

She saw the Pussycat Dolls on MTV and heard they were auditioning for a new group member. Melody went to the audition and was recruited in December 2003. For her audition, Melody only sang and was still accepted into the group. As with the other Dolls, she is a salaried employee of Interscope Records.
