In the 1987 Mexican telenovela Quinceañera, Thalía’s character is named Beatriz.
Beatriz is one of the two central young women in the series. Thalía plays her, while Adela Noriega portrays Maricruz Fernández. The contrasting lives of the two friends drive much of the program’s romantic, social, and family drama.
The telenovela premiered in 1987 and was produced by Televisa. It ran through 1988 and became an important early success for Thalía, who later built a major career as a singer and actress. The show is remembered both for its title’s connection to quinceañera culture and for launching or strengthening the public profiles of its young leads.
Maricruz is the most likely mix-up because she is the other principal girl in the story. However, Maricruz belongs to Adela Noriega, while Beatriz is Thalía’s role. The distinction is clear in the series’ central pairing and cast credits.
