In the image, the woman (possibly Aguilera) has long, curly dark brown hair and is wearing a jean jacket over a rhinestone outfit. Aguilera teased that more behind-the-scenes glimpses were on their way.

Aguilera recently signed on to guest-star on multiple episodes of the ABC country-music drama. She told The Hollywood Reporter last month that her character "is a successful pop singer who desperately wants to move into the country world, as that is her true passion. But she is caught between her passion and what the label wants her to do."

Hmm, could she be a potential signee for Rayna Jaymes' (Connie Britton) Highway 65 record label?

Nashville fans will have to stay tuned.
