David and Victoria Beckham are reportedly joining forces with Russell Watson for a charity Christmas record.
They plan to collaborate on a version of the song Nothing's Sacred Anymore.
Money raised would be in aid of six-year-old Kirsty Howard, who was born with her heart back to front.
She is being cared for at Francis House Children's Hospice where she has to breathe through tube attached to an oxygen tank.
A spokeswoman for the hospice appeal told the Daily Express: "The Beckhams are very positive and say they will be more than happy to get involved after the birth of their baby.
"They say Kirsty has made such a difference to their lives."
