The 34-year-old singer will appear on multiple episodes of the ABC series this spring. Aguilera will portray Jade St. John, a pop star who travels to Nashville to perform and explore her dream of recording a country album.
Aguilera's character will face resistance from her label, who wants her to remain on brand as a pop singer. E! News describes St. John as "a bird in a golden cage -- surrounded by her success, and trapped by it, too."
