“Skinnygirl Cocktail” mogul Bethenny Frankel has made a fortune with her low-calorie drink line, but fans began to worry about her weight after she posted a shocking photo to her Facebook page to promote her new recipe book. Frankel has always had a small frame, but it appears she might have taken things too far.

“My newest book #SkinnygirlCocktails comes out today!! Get it wherever books are sold! All of my favorite Skinnygirl party drink and snack recipes in one handy little book!,” she posted on her Facebook page Monday. More than 4,600 people “liked” the image, but thousands more commented.

“So I love love love Bethenny but I say this in the nicest way...she looks thin in an unhealthy way," Kristin Goldfine wrote. “I know she is tiny but compared to like her main pic this pic is a bit concerning.” Louise Versace Briglia simply wrote, “seriously too thin.”

The banner on the reality star’s Facebook page shows her sporting a fuller frame, where she looks healthy and happy. In the picture she posted Monday, she looks gaunt, rundown and there are dark circles under her eyes.

Frankel recently shocked people when she posted a picture of herself in her 4-year-old daughter’s pajamas. She defended herself and said Bryn asked her to put them on. "When ur 4 year old peanut says 'mommy please put my dress on' & giggles uncontrollably, u do what ur told,” she tweeted in July, according to Us Weekly.

A Manhattan judge has ordered the “Real Housewives of New York” star to stop wearing her daughter’s clothes, the New York Daily News reported Oct 2. Manhattan Supreme Court Justice Ellen Gesmer said no more pajamas. “It’s not a joke,” the judge said. “Her child is not a joke.”
