Cara Delevingne faced an unexpected holdup at the Stella McCartney show during Paris Fashion Week, being forced to wait in line after not being recognized by staff. The 33-year-old model, dressed in a sleek black "Come Together" tank top, jeans with lace-up leather chap panels and oversized sunglasses, appeared frustrated as she stood with her hands on her hips behind a group of guests in a video from the Tuesday, September 30, event that is now gaining traction on TikTok.
