David Walliams' 'Gangsta Granny' is to open on London's West End.

The 43-year-old comedian's top-selling children's book has been adapted by 'Horrible Histories' writer Neal Foster as a stage show and after a successful tour of the UK it is now heading to the capital's world famous theatre district opening at the Garrick Theatre on August 1, 2017.

'Gangsta Granny' has already earned a nomination for the UK Theatre Award for Best Show for Children and Young People.dd

The 'Britain's Got Talent' judge said: ''I'm delighted that my Gangsta Granny is making her West End debut. It's my most popular book so it will be wonderful to see the Birmingham Stage Company's terrific adaptation in dazzling neon next summer.''

Fans of the book will have until September 3, 2017 to see the show.

It comes after Walliams agreed to let the BBC have the TV rights to his books 'Billionaire Boy' and 'Awful Auntie', having seen two previous adaptations of his books get great ratings over the Christmas period.

He previously said: ''We are doing 'Billionaire Boy' this Christmas for the BBC and then, next Christmas, 'Awful Auntie'. It is very exciting.

''It's great seeing them on screen because you feel like a magician - something in your head becomes this real, physical thing.''

Walliams also suggested some big name stars are likely to feature in the new shows following the appearances of Miranda Hart and Robbie Williams in 'Gangsta Granny' and Hugh Bonneville in 'Mr. Stink'.

He said: ''We've had some incredible people cast, like Miranda and Robbie. It's great because the more you do of these films, if they turn out well, the more people are encouraged to get involved.

''I don't know who's going to be in 'Billionaire Boy' yet but there are a few good parts. And I'm sure I will pop up somewhere.''
