Award winning actress Martine McCutcheon will be raising money for St George's Hospital's neonatal charity on Sunday.
The Love Actually star is appearing on ITV game show All Star Family Fortunes in a bid to win £30,000 for the charity.
Miss McCutheon and her fiancé Jack McManus are patrons of First Touch, which gives support to premature and sick babies, families and staff who care for them in St George's Hospital.
Sarah Collins, charity manager, said: "We are delighted that our charity patrons Martine and Jack are trying to raise money for us on national television.
"Any money they do raise will be put towards buying essential medical equipment for the babies at the neonatal unit."
The show is being broadcast on April 29 at 7pm.
