Wearing a completely sheer LBD, the 43-year-old model's nipples were exposed thanks to the bright flashes of the paparazzi cameras.

Despite the fashion faux pas, Kate looked stunning in the all-black ensemble which also featured a stylish fur coat and suede boots. She finished off her look with a pop of red lipstick and slicked back hair.

This is not the first time the mother-of-one has "freed the nipple."

To make matters worse, the model ripped her gown, exposing way more than she intended.

"Since I was 14, [photographers] always got me to take my clothes off, even though I didn't like my body at all," she told W magazine. "I just had to get comfortable with it."

She continued, "Still, they ask me to take my clothes off. I have no idea why. I really don't get it at all."

Today, her younger sister Lottie is launching her own modeling career, and Kate has some advice for her mini-me.

"Kate says that if she wants to capitalize on the media furor surrounding her, the smart move is to leave school. Kate left school at a young age and never looked back," a source told the Daily Mail.
