Holly Willoughby brings some Christmas sparkle into the lives of some of the nation’s most inspirational people in a special festive edition of the show. Olly Murs performs for two women from Sheffield who organise an annual Christmas dinner for over 300 people who would otherwise be alone. Britney Spears dresses up as a Savoy butler and surprises a special brother whose two nephews have cerebral palsy. Torvill and Dean skate with a remarkable 91-year-old who has been a volunteer teaching ice skating in Scotland for nearly 50 years, and four sisters are reunited to spend their first Christmas together since 1949. Michael Buble, Cher and Phillip Schofield join in the fun by surprising unsuspecting members of the studio audience.
