Toñi Moreno was born in El Prat de Llobregat, when her father worked at SEAT, but at age 8 her family moved to Cádiz. She later studied law there, although her vocation was journalism. In 1985, at age 12, Moreno began her radio career on the station Radio Sanlúcar. At age 14, she left the world of voiceover to begin working at Telesanlúcar, the local television station in Sanlúcar de Barrameda. There she made her on-air debut. Later she joined Canal Sur, where she was a reporter for the program Andalucía directo [es]. Since then, she has had an extensive professional career in television, working on shows linked to the regional autonomy of Andalusia such as Tiene arreglo [es] and 75 minutos, which she was on for eight years. After her departure for private television, on Antena 3 she hosted the reality show Libertad vigilada [es], coordinated the morning magazine Cada día, and worked as a reporter.
