Jessica Simpson was told to "put your shirt on," but the 40-year-old bombshell didn't fall short on the compliments for her latest – and very topless – snap. Jessica, who famously dropped 100 pounds in 2019 after welcoming third baby Birdie Mae, has been making headlines galore for her whittled-down frame – for some, Jessica is "way too skinny."

A photo of Jessica in nothing but a pair of jeans is now being used to promote the "Dukes of Hazzard" star's clothing line. Scroll for the shot, plus the reactions.

Jessica's beach shot is below. It comes as the "Open Book" author – who fronted media outlets earlier this year for dropping the candid memoir – sees sales of her book spike as millions lead new lives from home.

Also alive and well, is the Jessica Simpson Style clothing line that raked in a reported $1 billion in 2015. This photo came promoting the brand's jeans, with Jessica seen photographed from behind, on a rocky beach, and looking drop-dead gorgeous as she highlighted both her curves and new-found skinnier body for a topless bombshell finish.

A caption from the popular clothing brand read: "Sometimes all you need is the perfect pair of jeans! ✨ Link in bio to shop our favorite #JessicaSimpsonDenim."

Comments have been coming in – some without words: "???????," one fan wrote. "Yesssssss honey rock them jeans!! ????," anothersaid, with the singer and actress also being called "such a BABE."

Feedback was not so positive as Jessica turned 40 earlier this month and chose to wrap up the final hours of her thirties in a 14-year-old pair of True Religion jeans. More below.

Jessica, who announced her 100 pound drop in September 2019, sparked concern with her last thirties selfie. The mom of three had her 5.4 million followers pretty concerned that she may have taken the weight loss too far.

As The Blast reported, Jessica was told: "You're shrinking so fast it's scary ? Be safe beautiful." While a popular comment told the star she was "way too skinny," and another dubbed the photo "the look of anorexia." One fan focused on Simpson's proportions:

"Omg looks like her head isn't attached to her body. Scared me," they wrote. Scroll for how Jessica dropped the weight.

Jessica walked up to 10,000 steps a day to lose the weight. The star who is, herself, a winner of chili cook-offs, also watched the calories, as trainer Harley Pasternak told Hollywood Life:

“She would eat one whole egg and three egg whites for breakfast, scrambled with a bowl of blackberries. For lunch she would have a salad with grilled chicken and grilled fish with salad and vegetables for dinner."

Jessica has also been showing off her ripped frame in gym wear. Scroll for the skimpy lycra shot seeing the star sweat-drenched and in workout mode.
