The TV star and author will be watched by Kathleen when he is presented with an OBE by the Princess Royal in recognition of his services to charity and the arts.
Walliams, who was named in the Queen’s birthday honours in June, said at the time: “The News made me happy, but nobody is happier than my mum.”
On Monday, he posted a picture of a model version of the palace on Twitter and wrote: “I am looking forward to taking my mum to Buckingham Palace tomorrow (the real one not the Lego one)…”
Double Olympic champion and Army Major Heather Stanning will receive an OBE for services to rowing during the ceremony, while former prima ballerina Dame Beryl Grey will be made a member of the Order of the Companions of Honour for her contribution to dance.
Walliams and comedy partner Matt Lucas became household names in the early Noughties with BBC sketch show Little Britain.
The programme, in which they mocked British stereotypes, was an international hit and won a handful of TV Baftas.
Walliams is also known for being a judge on Britain’s Got Talent and recognised as one of the most popular children’s authors of a generation.
His books, including 2008 debut The Boy In The Dress, and follow-ups Mr Stink, Gangsta Granny and Ratburger, have topped best-seller lists.
Away from TV and literature, Walliams has generated millions for charity, swimming the English Channel in 2006 and taking on the Strait of Gibraltar in 2008.
In 2011, he raised £2 million for Sport Relief by completing a challenging 140 miles down the River Thames.
