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 today 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 on Monday morning at the property in Manhattan and it is understood that police do not suspect foul play.

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 early on Monday ahead of a performance at the Perth Arena, in the west of the country, which had been scheduled for today.

Last Sunday 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 4in 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.
