Lily Allen has performed a cover of Keane's 'Somewhere We Only Know' for the new John Lewis Christmas advert.

The Brit can be heard singing a stripped back version of the hit song for the commercial, which was unveiled this morning (November 8).

The animated advert sees a hare spend time with a bear, before the latter has miss out on all the Christmas fun by hibernating over winter.

However, the hare places a present - an alarm clock - next to the sleeping bear so that the animal can awaken to celebrate Christmas.

The advert's blurb says: "Watch the new John Lewis Christmas TV advert and see Hare give his best friend Bear a Christmas he'll never forget. Set in a beautiful forest, poor Bear is the only animal that never gets to celebrate Christmas because he has to hibernate every year. However, this year is different. This year Hare has a brilliant idea."

Allen meanwhile has been in hibernation herself after taking a break from music, but she has returned to the studio to work on her next album.

Her previous record came in the shape of 2009's 'It's Not Me, It's You'.
