- BY MARK JEFFERIES Showbiz Editor

LITTLE Britain's David Walliams has told of his pain at not spending Christmas Day with his son.

The comedian has 12-year-old Alfred with ex-wife Lara Stone, 41, and it's her turn to have him on December 25.

Walliams, 54, said he explored his sadness in his new book Santa & Son, about a boy called Elvis who is being brought up by his single mum.
