L'Wren Scott rocked the fashion industry and Rolling Stones' front man Mick Jagger's world -- and sadly, in death the fashion designer and former model shocks the public with the news of her alleged suicide.

Scott, who was romantically linked to Mick Jagger since 2001, was found dead in her Manhattan residence around 10 a.m. on Monday, March 17, by her assistant, according to several reports.

While a cause of death has yet to be determined, the 49-year-old was found hanging from a scarf on a doorknob, and sources told the paper foul play is not suspected.

Jagger, 70, who is currently on tour in Australia with his band, is reportedly "completely shocked and devastated by the news."

Back in 2012, Jagger was invited to play at a concert in the East Room of the White House in recognition of Black History Month. Both he and Scott attended the performance, which was called Red, White, and Blues and also featured B. B. King, Buddy Guy, Keb Mo and Gary Clarke Jr. Trombone Shorty, CNN reports. 

The couple shared their enthusiasm for meeting President Obama via Twitter.

"Met President Obama who listened to a few tunes during rehearsal he seemed really relaxed and happy!" Jagger tweeted.

Meanwhile, L'Wren Scott, Jagger's longtime girlfriend, tweeted it was "amazing to meet the president" and "loved every moment."

While Scott was thrilled to meet the president, she had a connection to First Lady Michelle Obama -- she designed for her in addition to Spanish actress Penélope Cruz, Jennifer Lopez, Angelina Jolie, Sarah Jessica Parker, Amy Adams and Nicole Kidman, among many others.

Scott's approach to designing clothing appealed to all women, highlighting the feminine form, even though the fashion designer and former model was a 6'3, statuesque beauty who wore everything well.

"That willingness to listen and act on the reactions of both her friends and the well-dressed strangers who buy her clothes is why Scott has become a go-to for the kinds of real clothes that real women crave, Vogue reported. "Her figure-flattering, curve-creating dresses allow, even encourage, women to feel comfortable and confident. And you can't put a price on that."

The Utah native also drew inspiration from artists -- specifically painter David Hockney.

Back in 2012, the fashion season was set off by the Royal Academy of Arts' Hockney exhibit that Scott called "one of the most amazing things I've ever seen." She was "particularly inspired by the painter's use of graphic strokes and strong colors and interpreted them in varied ways," Vogue added.

News of Scott's death has impacted many in the fashion industry, including cosmetics mogul Bobbi Brown, "I am devastated by the tragic news about L'Wren. She was a visionary designer who I very much enjoyed working with, but she was also smart and kind," Brown said. "My thoughts and heartfelt condolences go out to her loved ones during this very sad time."
