"There are so many who need homes," explains Cuoco, who passionately advocates shelter adoption. "[It's] such a good idea to adopt them and they love you forever for it. It's like they know."

"I wanted to do a book about hope and a book about love," said Bruynbroek to ET. "Some of them are mutts, some of them are pure-bred, and it's just to show that love is not something you buy."

Ellen DeGeneres, Jackie Chan, Kim Basinger and Brigitte Bardot are also featured in the collection, available now.
