The death of L’Wren Scott, the high-end fashion designer who was the longtime girlfriend of Mick Jagger, caught by surprise fans and friends alike.

One of the first to offer condolences was Jagger’s first wife Bianca, who posted on Facebook: “Heartbroken to learn of the loss of the lovely and talented L’Wren Scott. My thoughts and prayers are with her family. May she rest in peace.”

Scott, who left Utah as a teenager to become a model in Paris, was found in her Manhattan apartment on Monday from an apparent suicide. No note was found and there was no sign of foul play, police said.

Investigators said the Hollywood designer has texted her assistant 90 minutes earlier and asked her to come to the apartment, but gave no reason as to why. Scott was found kneeling with a scarf wrapped around her neck that had been tied to the handle of a French door, police said.

Her spokesperson requested privacy for her family. A representative for Mick Jagger said the singer “was completely shocked and devastated by the news” of her death.

The Rolling Stones frontman, who canceled a concert in Australia to fly to New York, posted a poignant tribute Tuesday on Facebook, saying he is still struggling to understand her death and will never forget her.

“We spent many wonderful years together and had made a great life for ourselves,” Jagger wrote. “She had great presence and her talent was much admired, not least by me.”

Bianca Jagger, a Nicaraguan human rights activist who was married to the singer from 1971 to 1978, also commented on Facebook about the media’s coverage of Scott’s death, calling it sexist.

“Appalled at the sexist reporting, lack of compassion and lack of respect for L’Wren’s accomplishments by most world media,” she wrote.

Scott, whose elegant designs in lush fabrics were favored by celebrities like Madonna, Nicole Kidman, Oprah Winfrey, Penelope Cruz and first lady Michelle Obama, was a fixture on Jagger's arm since they met in 2001. On red carpets, the striking 6-foot-3 designer towered over her famous 5-foot-10 boyfriend.

Scott is survived by a brother, Randall Bambrough of Ogden, Utah, who declined comment.
