UPDATE: Bethenny Frankel tweeted Monday in response to the backlash, writing, "BREAKING NEWS! World Scandal: Former reality star, failed talk show host & cocktail maven jokes by wearing her kids' pjs! #itcantbetrue"
"When ur 4 year old peanut says "mommy please put my dress on" & giggles uncontrollably, u do what ur told," she added.
She followed up a few hours later with: "What will be convenient & economical is if I have another baby & wear their diapers when i'm in adult diapers. #frugalmom"
Little girls often play dress up in mom's clothing, but Bethenny Frankel took the opposite approach.
On Sunday, the 43-year-old SkinnyGirl mogul Instagrammed a photo of herself wearing 4-year-old daughter Bryn's Hello Kitty nightgown and pajama shorts, asking, "Think we're ready to start sharing clothes yet?"
The full-body shot was cute to some and controversial to others, who deemed the pic "inappropriate" and wondered if it was "sending the wrong message" to young girls. This, though, isn't the first time the Naturally Thin author has come under fire for her fit figure.
