Some of Hollywood's biggest stars appear in this new coloring book for adults. Illustrator Mel Elliott has created 'Color Me Swoon', which sees the likes of Brad Pitt, Ryan Gosling and Zac Efron posing in black-and-white illustrations that fans can color in. Readers can also rate the male stars with marks out of 10. 'Color Me Swoon: The Beefcake Activity Book for Good Color-Inners as well as Beginners' will hit shelves on September 3. "Color Me Swoon will leave you weak in the knees as you and your pens caress chiseled features and chest hair," publishers Perigee promise. "Along with coloring, you'll rate more than sixty gorgeous guys on swoon-worthy-ness, as well as learning what in their lives (beyond their killer looks, duh) makes them so hot." British-based Mel hit headlines last year when she created the Ryan Gosling 'Colour Me Good' book.
