The singer has premiered a cover of the 1943 festive favourite 'I'll Be Home For Christmas', which is expected to be released digitally in the coming weeks.
The song was written by Kim Gannon, Buck Ram and Walter Kent in the '40s and has since been covered by a range of artists including Michael Buble and Elvis Presley.
Clarkson has performed the track during previous Christmas concerts, but this is the first time fans have got to hear a studio version of the song.
The American Idol champion recently confirmed that she will release 'What Doesn't Kill You (Stronger)' as the second cut to be lifted from her Stronger album.
