David Walliams' new book called The Bear Who Went Boo!
TV star David Walliams has announced the name of his new picture book is The Bear Who Went Boo!.
The Britain's Got Talent judge has teamed up with award-winning illustrator Tony Ross again.
The Bear Who Went Boo! is Walliams' fourth picture book and will be published in hardback on November 5.
The book tells the tale of a "very cheeky polar bear cub" who loves startling other animals.
Speaking about the book, Walliams said: "Tony Ross has done a magnificent job bringing my words to life."
Ross, best known for illustrating the Horrid Henry series, said: " A white bear in a white landscape - definitely a challenge, but a new text from David Walliams - always a delight."
Walliams has also enjoyed success publishing several fiction novels for children.
His most recent novel, Awful Auntie, has sold more than 657,000 copies and was also named the biggest selling book, across all categories, published in 2014.
HarperCollins children's books executive publisher Ann-Janine Murtagh said: " David Walliams brings his storytelling magic to the picture book market once again this Christmas."
"His deliciously funny new tale features a small polar bear who is all set to be a big hit with his growing number of younger fans."
"Tony Ross' joyful illustrations are the perfect partner - full of his inimitable mischief and fun. The Bear Who Went Boo! affirms that David Walliams is now a major force in picture books alongside his phenomenal fiction."
"It is sure to be a smash hit and supercharge the picture book market this Christmas."
