Most likely the most rebellious student in Elite Way, Roberta is the only daughter of Alma Rey (Ninel Conde), a famous singer who gave birth to Roberta when she was very young, supposedly with her first husband, Mr. Pardo. However, Roberta eventually finds out that her biological father is Martín Reverte, a teacher at Elite Way, who joined the school in order to find his child. Roberta is a reckless, strong young girl with a short temper and a big heart. She has the tendency to find problem wherever she goes, not only for herself, but for others too, but she always finds inventive ways to work her problems out. She's the co-female lead of RBD along with Lupita and Mia, with whom she at first has a difficult and conflicted relationship (Roberta thinks Mía's too ditzy, dumb and shallow). Her best friends are her roommates, Lupita and Jose Luján.
