Lily Allen is rumoured to sing on this year's John Lewis Christmas TV commercial.
The Brit-winning singer is thought to have recorded a cover of Keane's Somewhere Only We Know for the ad, industry insiders have told Music Week.
Other options are also being considered for the Christmas 2013 campaign, which is expected to premiere in coming weeks, the sources claimed.
The trade magazine also said that Annie Lennox was "heavily considered" to lend her vocals before Lily was picked, and that two-time Mercury Prize-winner PJ Harvey was approached by the creative team behind the commercial.
In the past, the John Lewis Christmas campaign has featured covers by up-and-coming British artists including Ellie Goulding, Amelia Warner and Gabrielle Aplin.
Ellie's rendition of the Elton John classic Your Song reached the top spot in the iTunes chart in 2010, and Gabrielle's cover of Frankie Goes To Hollywood's Power Of Love went on to become a UK number one in 2012.
Lily, who took a four-year break to focus on starting a family, has been working on her third studio album, which is expected to be released in spring 2014.
