The former Baywatch star will read kids' favourite My Friend Nigel by Jo Hodgkinson on children's cable channel CBeebies on New Year's Eve (31Dec12).
He joins a host of stars who are reading stories during the festive period, including singer Lulu, actress Emilia Fox and Sir Derek Jacobi.
Hasselhoff admits he can't wait to take part in the show, insisting he's loved books since the Christmases of his youth.
He says, ""I think it is so important for children to become familiar with books from an early age.
""As a child I used to love reading 'Twas The Night Before Christmas and I can still recite all the words today.""
