Jennifer Hudson has been the highlight of many conversations as of late for her dramatic weight loss, which she details in her new book, 'I Got This: How I Changed My Ways and Lost What Weighed Me Down,' released last month.

The former 'American Idol' contestant and 'Spotlight' singer, who's a current spokesperson for Weight Watchers, is also showing off her new figure with form-fitting dresses and has even given fans a peek at her bare stomach.

While seated in a chair apparently getting her nails done, Hudson snapped a photo of herself wearing a midriff-baring top that exposed her slim physique. The 'Dreamgirls' star flaunted her flat stomach on Twitter, causing some of her followers -- or should we say critics -- to question her weight loss.

"and what does bulimia have to do with me, Absolutely nothing. I do weight watchers! [sic]" she asked Twitter user @MenteshHussein.
