Police said L'Wren's assistant found her body hanging from a scarf on a doorknob at around 10 a.m., according to the New York Daily News. Earlier that morning, Mick Jagger's 47-year-old girlfriend texted her assistant at 8:30 a.m. and asked her to come over. The assistant found the body when she arrived and called 911.
The Medical Examiner's Office will determine a cause of death, but for now police don't suspect foul play.
Mick released a statement via a spokesperson that he is "completely shocked and devastated" by the news of her passing. The duo first met in 2001 and had been dating since then.
Prior to her successful career as a fashion designer, the 6'4 beauty began her career as a model in Paris before moving to Los Angeles to become a stylist.
