Christina Aguilera releases second 'Nashville' song

Los Angeles: Singer Christina Aguilera has released the studio version of ‘Shotgun’ for the TV series ‘Nashville’, following last week's ‘The Real Thing’.

The song was released on Tuesday, and unlike the upbeat ‘The Real Thing’, the new song is a slow-tempo ballad on which she's accompanied only by simple acoustic guitar licks, reports aceshowbiz.com.

Aguilera makes a guest starring appearance on ‘Nashville’, playing a pop star named Jade St. John. She will perform ‘Shotgun’ in the Wednesday, episode of the ABC series.

The 34-year-old songstress is currently also serving as a coach on ‘The Voice’ while readying her new album
