The Rolling Stones have cancelled an imminent concert in Australia following the death of designer L'Wren Scott, the girlfriend of lead singer Sir Mick Jagger.
The 49-year-old model and designer, who had been dating the Rolling Stones frontman since 2001, was apparently found hanged at a New York apartment.
Frontier Touring, the promoter of the band's world tour, posted a message on its Facebook site to confirm a concert in Perth tomorrow will not go ahead.
It said: "No further information is available at this time, ticket holders are asked to hold on to their tickets until a further update is available."
Speculation had mounted about the future of the tour following news of Scott's death, with the band due to perform six dates in Australia and New Zealand over the next three weeks.
Tributes have poured in for the 49-year-old model, as it emerged her British fashion company had been losing millions of pounds.
Her body was discovered yesterday morning at the property in Manhattan and i t is understood that police do not suspect foul play.
A spokesman for Sir Mick said: "He is completely shocked and devastated by the news."
Accounts filed with Companies House in October show Scott's British company, LS Fashion Ltd, was running at a loss of more than £3.5 million in 2012, up from more than £2.5 million the previous year.
The documents also show the firm owed more than a million pounds, despite having assets totalling a similar amount.
The Rolling Stones had flown to Australia yesterday ahead of a performance at the Perth Arena, in the west of the country, which had been scheduled to take place tomorrow.
Three days ago they had played a show at the grand ballroom of Singapore's Marina Bay Sands, rounding off the Asian dates of their 14 On Fire tour.
Scott, who was said to be 6ft 4ins tall and towered at least half a foot over her boyfriend, became well-known in Britain after she got together with Sir Mick.
She designed stage outfits for notable performances at Glastonbury Festival and Hyde Park in recent years.
Sir Mick was there to support her when Scott showcased her collection in her debut London fashion show last year.
As news broke of her death, tributes from the world of fashion and showbusiness flooded on to Twitter.
Bianca Jagger, one of Sir Mick's former loves, tweeted: "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."
Fashion designer Marc Jacobs wrote: "Rest in peace, L'Wren Scott. You'll forever be missed."
Pop band Duran Duran added: "Such sad news. Our condolences are with L'Wren's family and friends."
Model Daisy Lowe tweeted: "What a loss to the world. Such an inspired woman. She dressed the feminine form unlike any other."
Entertainer Bette Midler wrote: "Just got news of the beautiful L'wren Scott's death perhaps by her own hand. I am devastated. A rare, wonderful, talented soul. Goodbye."
And actress Emmy Rossum tweeted: "So sad to hear of the death of L'Wren Scott. What a beautiful woman and an incredible designer".
Scott, who was originally called Luann Bambrough but changed her name to launch her modelling career in her teens, was brought up in Utah as a Mormon.
She worked in Paris for a number of years, with the likes of Thierry Mugler and Karl Lagerfeld, then went on to return to the US as a stylist. The designer was a wardrobe consultant for films such as Eyes Wide Shut and Ocean's Thirteen.
She met Sir Mick, 70, when she worked as a stylist on a photo shoot. She launched her fashion line in 2006 with fans of her work said to include Sarah Jessica Parker, Nicole Kidman and Michelle Obama, and she has also designed for Banana Republic.
