Sad news for Rolling Stones legend Mick Jagger as WABC is reporting that his girlfriend, L'Wren Scott, was discovered dead inside her New York City apartment Monday morning (March 17).

According to the New York Daily News, she was discovered at her apartment by her assistant at just after 10AM ET. Reports suggest that the death was an apparent suicide, as she was found hanging from a scarf tied to a doorknob. The Medical Examiner will still complete an exam to determine the exact cause of death. No suicide note was found.

The 49-year-old Scott was a model and designer, known for dressing actresses Christina Hendricks, Penelope Cruz and Nicole Kidman, among other celebrities, for red carpet events. Scott had canceled a London Fashion Week show in February due to production issues. She and Jagger had been dating for over a decade.
