Jennifer Aniston is teaming up with her father John to narrate a series of children's books for charity.
Aniston will be the voice of a giraffe named Daisy in story that will be mostly narrated by her Dad.
The book, entitled Good Deeds by Nick Katsoris' Loukoumi collection is the third release in an ongoing series about doing nice things for other people.
Katsoris tells RadarOnline.com, "Jennifer was wonderful, they were so easy to work with and it was the first time they had done something together. They recorded in L.A. last fall and she was just a joy to work with.
"All the proceeds go to St. Jude's and Jennifer is a big fan of them."
A rep for Aniston adds, "It is a wonderful story, plain and simple. She did it because she wanted to do it with her dad, as well as she loved the story.”
The entire novel will be accompanied with a CD and will be available on April 1, 2009.
