Christina Aguilera has given fans a quick preview of her upcoming guest role on Nashville.

The singer has now begun filming scenes for the US TV series.

Speaking on Twitter on Monday (March 9), Aguilera said:

"Look at all that hair! Having lots of fun on the set of #Nashville. More to come!"

The text accompanied a picture of Aguilera's back as she sat on a chair.

The images sees the US star wearing a long dark wig.

Speaking previously about her guest role, Aguilera said:

"I am excited to try something different, as I do think in life, and in music, experience just adds to the creative process.

"We haven't started shooting, I actually leave for Nashville next week. But I can say my 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.

"I have started to venture into all aspects of the business, still with my focus on music, but acting and now even producing TV. We just sold our idea to ABC Family so it's an exciting time for me."
