The Sports Illustrated model, who is married to R&B singer John Legend, bought the best-selling erotic novel by E.L. James to read on holiday in Mexico but wasn't impressed by its "horrendous" content.
The 28-year-old star shared her reading plans on Twitter on Thursday (26.12.13), writing: "Need a book for our holiday away. Kind of want to read '50 shades' and basically mystery science library it for you via twitter. (sic)"
But a day later she admitted that she had already thrown in the towel.
Chrissy tweeted on Friday (27.12.13): "Annnnd I'm done. 2 pages in thank you for enjoying mystery science library. (sic)"
She then attempted to read it again, before writing: "I have an extremely high pain tolerance. But I honestly don't think I can do this. This book is f**king horrendous."
She considered "throwing" the novel "in the ocean" before she came up with the idea to bury it on the beach.
The brunette beauty also posted a picture showing her digging on hole in the sand for the book on Instagram, with the caption: "I tried."
The 'Fifty Shades of Grey' film will be directed by Sam Taylor-Johnson and will star Jamie Dornan as Christian Grey and Dakota Johnson as Anastasia Steele.
The film is due for release in February 2015.
