Jennifer Hudson has shed 80 pounds over the last year or so, accomplishing the sort of weight loss goals many women dream about.

How did the Weight Watchers spokeswoman do it? You'll have to buy her upcoming book to find out.

The former American Idol finalist and Oscar winner will pen a memoir that chronicles her "experience growing up in an environment where healthy living was not a priority," according to a statement by publishing company Dutton.

The book will delve into "her weight as she competed on American Idol and won her first Oscar," along with her "eventual decision to get healthy after the birth of her son, and her success losing weight with the help of Weight Watchers."

No word yet on whether Hudson will touch on the tragic family murders that took place in 2008.

She will reportedly be paid $1 million for the effort and  "wants to inspire anyone coping with weight issues, share some of her own best tips for losing and maintaining weight loss, fitting in exercise and keeping it fun," Dutton says.
