Ellie Goulding is to release the official 2013 Children in Need single.

The star will release 'How Long Will I Love You' in support of this year's campaign.

Could she perform the song on this weekend's result show?

I don't know how that could possibly work. It would surely melt the collective DS brain if a successful artist with a small and very quirky voice (who isn't trying to be Whitney or Mariah) were to perform on the X Factor......
