Christina Aguilera has gone country … well, sort of.

The Voice mentor will guest star on Nashville – and PEOPLE has an exclusive first look at the singer in character.

Aguilera, 34, will play Jade St. John, a pop superstar who has always wanted to record a country album but has been shackled by her label to stay “on brand in the pop world,” according to ABC.

And in true Nashville fashion, Aguilera’s character will also have a dramatic connection to one of the ABC drama’s other characters: Jade is the ex-fiancée of former music exec Jeff Fordham (Oliver Hudson).

“Jeff is forced to revisit his past and work with the woman who once played a large role in both his personal and professional lives,” says the network.

Aguilera’s first episode of Nashville airs April 15 at 10 p.m. ET on ABC.

Nashville airs Wednesdays (10 p.m. ET) on ABC.
