NEW YORK (WABC) -- Mick Jagger's girlfriend, designer L'Wren Scott, was discovered dead inside a Chelsea apartment Monday morning.
The 49-year-old model and designer was found by her assistant inside the apartment on 23rd Street and 11th Avenue just after 10 a.m.
She was discovered kneeling with a scarf around her neck that had been tied to a door handle in what police believe was an apparent suicide, although the Medical Examiner will determine the exact cause of death.
No note was found in the home, and no criminality is suspected.
The designer had texted her assistant 90 minutes earlier and asked her to come to her apartment but didn't say why, police said.
Mick Jagger's spokesman released a statement, saying "(Mick) is completely shocked and devastated by the news."
The pair had been dating since 2001.
The Utah-born Scott had her own fashion label popular with celebrities. She was a fixture on Jagger's arm and, at around 6-foot-3, towered over her famous boyfriend.
She founded her high-end label in 2006 and recently created a more affordable line of clothes with Banana Republic.
On the red carpet, she has dressed stars like Nicole Kidman, Oprah Winfrey, Sarah Jessica Parker and Angelina Jolie.
Just last month, she canceled her London Fashion Week show due to reported production delays.
Makeup artist Bobbi Brown collaborated with Scott last month on a cosmetics line called the Bobbi Brown x L'Wren Scott Collection.
"I am devastated by the tragic news about L'Wren," Brown said on her website. "She was a visionary designer who I very much enjoyed working with, but she was also smart and kind. My thoughts and heartfelt condolences go out to her loved ones during this very sad time."
The Rolling Stones canceled their scheduled concert in Perth, Australia, Tuesday night. It is unclear if or when the rock band will resume their tour.
