Marina And The Diamonds covers 'Have Yourself A Merry Little Christmas' - watch
Marina Diamandis sings an acoustic version of the festive classic
Scroll down to watch the singer's rendition of the song, in which she is backed by an acoustic guitar.
The song originally featured in the 1944 musical film, Meet Me In St Louis, where it was sung by Judy Garland.
It has since been covered by a host of classic artists, including Frank Sinatra, Ella Fitzgerald and James Taylor.
Earlier this year, Diamandis admitted that she was worried people "wouldn't allow" her to become a pop star.
The singer's second album 'Electra Heart' - released earlier in 2012 - was a drastic change in direction from her debut LP 'The Family Jewels' and, in an interview with Drowned In Sound, Diamandis revealed she had had concerns about alienating her fanbase.
''I think that I wasn't allowed to change and that deep down I wanted to write a pop album and to be a popstar," she said. ''For some reason, I felt like people wouldn't allow me to do that, which is stupid because I love the album."
In September, the singer hit the headlines after she claimed that her record label Atlantic had delayed the release of the video for her track 'How To Be A Heartbreaker' because she looked "ugly" in it.
