Scottish singer Susan Boyle has become one of only a handful of artists to be granted permission to record a posthumous duet with the late Elvis Presley.
The star has recorded a new version of Christmas carol Oh Come All Ye Faithful, which will feature on her upcoming holiday album Home For Christmas.
The track includes vocals from The King of Rock 'n' Roll, which have been added using studio technology.
Boyle has dedicated the song to her late father, who was a huge fan of Presley.
"To put a unique twist on classic Christmas songs is truly wonderful. I grew up listening to Elvis and to sing with him, well, I didn't think it would be possible. Isn't technology brilliant? The track is for my father - and for Elvis."
Celine Dion has previously recorded a posthumous duet with Presley, along with his daughter Lisa Marie Presley.
Boyle's album also features a collaboration with crooner Johnny Mathis.
