L'Wren Scott, the girlfriend of Rolling Stones frontman Mick Jagger, has been found dead aged 49.
Ms Scott, who had remained in New York while Sir Mick was on tour in Australia with his band, had in recent years seen her dresses make the Oscars red carpet and the White House wardrobe of Michelle Obama.
Her body was found on Monday morning in her flat in a luxury high-rise tower in the Chelsea district of Manhattan by an assistant. Reports suggested Ms Scott was found hanged, and had earlier had texted her assistant to come over.
Officials said there was no suggestion of foul play, although a final of cause of death was to be determined by the city’s medical examiner. There was no note found at the apartment.
A spokesman for Sir Mick, who had been linked to Ms Scott since 2001, said the singer was “completely shocked and devastated” by the news.
Raised by adoptive parents in Utah, Ms Scott stood at six foot, three inches tall. Soon after leaving high school she was spotted by the photographer Bruce Weber at a Calvin Klein shoot.
At his suggestion, she travelled to Paris where she became a model for such names as David Bailey and Chanel. By the early 1990s she had moved to California. As a stylist, her early assignments included the advertising campaign for Elizabeth Taylor’s White Diamonds perfume.
She emerged as a sought-after fashion designer to Hollywood royalty, contributing costumes to films including Eyes Wide Shut and Ocean’s Thirteen.
She also worked on a Martin Scorsese 2008 documentary about the Rolling Stones, when she was already many years into her relationship with Mr Jagger, who is 70.
Ms Scott came out with her first own-label collection in 2006, called “Little Black Dress”. After that, her creations were selected by several stars for Oscar nights including Amy Adams, Nicole Kidman and Penélope Cruz.
It was rumoured she had been picked to design the wedding dress for Angelina Jolie, expected soon to tie the knot with Brad Pitt. Other celebrities known to have worn her dresses have included the First Lady and Oprah Winfrey.
She had recently also launched a more affordable line of women’s fashion with the Banana Republic chain of clothing shops. The only possible indication of professional trouble was the cancelling of her runway show for London’s Fashion Week, due to reported production delays.
Earlier on Monday, Mick Jagger and his bandmates had touched down before dawn in Perth, Australia, to kick of their “On Fire” tour of the country. He was seen walking on a local beach in the late summer sun just hours before the news broke of his partner’s death.
Among those paying early tribute was Bianca Jagger, the rock star’s former wife. On Twitter she posted: “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.”
Fellow fashion designer Marc Jacobs tweeted: “Rest in peace, L’Wren Scott. You’ll forever be missed.” Pop band Duran Duran tweeted: “Such sad news. Our condolences are with L’Wren’s family and friends.”
Rocker's long trail of loves over the decades
By David Mercer
Sir Mick Jagger's relationship with model L'Wren Scott, who was more than two decades his junior, was the latest in a string of high-profile romances for the Rolling Stones frontman.
The 70-year-old singer, who has seven children by four different women, dated model and actress Chrissie Shrimpton from 1963 to 1966 and Marianne Faithfull from 1966 to 1970.
His first child was with fellow singer Marsha Hunt before, in May 1971, he married Nicaraguan Bianca Perez Morena de Macias, later known as Bianca Jagger, a social and political activist.
Later that year, Bianca gave birth to Sir Mick's second child – Jade Jagger – but the couple separated in 1979 and divorced in 1980.
After separating from Bianca, Sir Mick became involved with British-American supermodel Jerry Hall (left).
The couple, who have four children together, were married in 1990 in Bali but their marriage was later disputed since it was not properly conducted, and was subsequently shown to be invalid.
Hall separated from Sir Mick in 1999 after model Luciana Gimenez claimed she was pregnant with his child, which was proved to be true by DNA tests.
Sir Mick has also previously been linked with Carla Bruni, now married to former French president Nicolas Sarkozy, and in October, he was forced to deny a claim by singer Katy Perry that he made a pass at her when she was a teenager.
