The Sun report that Louis was scheduled to perform his latest single Two Of Us as part of the BBC's Comic Relief live coverage on Friday but has since pulled out of the fundraiser.
The song is a tribute to the singer's late mother and includes the lyrics: 'You'll never know how much I miss you. The day that they took you, I wish it was me instead.'
