Kate Moss' sister Lottie has said that she checked into rehab because she has a "really bad addition to coke".
The 24-year-old model took to her TikTok account, where she has amassed 25.8k followers, and spoke about entering the treatment centre last month.
Donning a pair of loosely plaited pigtails as she looked into the camera, the words on screen read: "When people ask why I'm in rehab."
