Nashville - Christina Aguilera gets multi-arc story

The Voice coach Christina Aguilera – who just graced the cover of PEOPLE with her infant daughter, Summer Rain – will join the ABC drama for a multi-episode arc this spring, PEOPLE has learned exclusively.

Aguilera, who will return to NBC's talent show on Feb. 23, has been cast as Jade St. John, a pop superstar who’s been going pretty much non-stop since she broke out a decade ago. She arrives to Nashville for a two-night stand at the Bridgestone, but her real dream is to record a country album – if only her label, who wants her to stay on brand as a pop star, would let her break out of her golden cage.
