The Rolling Stones have cancelled the first show of their Australian tour.

Lead singer Sir Mick Jagger is currently grieving following the death of his long-term fashion designer partner L'Wren Scott. She was found dead of an apparent suicide in her New York City apartment yesterday.

Mick and his bandmates touched down in Australia yesterday, where they were due to commence shows tomorrow. It has now been confirmed they will not take to the stage in Perth.

"No further information is available at this time, ticket holders are asked to hold on to their tickets until a further update is available," promoter Frontier Touring said in a statement.

The Rolling Stones were due to play seven dates of their On Fire show in Australia and New Zealand, ending on April 5. At the moment there is no information about whether any of the other performances will go ahead.

Following the news of L'Wren's passing, Mick's representative said he was "completely shocked and devastated" by her death.

The MailOnline has published a photograph of him looking shaken as he leaves a Perth restaurant, apparently shortly after he had received the news. The rocker had been dating 49-year-old L'Wren since 2001 and has been forced to rubbish speculation they were not together at the time of her death.

"Everybody who knows L'Wren and Mick are totally and completely shocked. Neither of them drink and do drugs, and they were always really affectionate with each other. There were no signs of problems in their relationship," a source told MailOnline.

The designer's body was discovered by her assistant at 10am local time, with claims she had texted the person to come to her property at 8.30am. Reports claim L'Wren had hanged herself with a scarf from a doorknob, although an official report hasn't been released yet. There was no suicide note at the scene.

Her fashion company is understood to have been experiencing intense financial difficulties over the last few years, with MailOnline claiming the issue left her feeling embarrassed and stressed. In October 2013, accounts show it had a deficit of $5,899,548 and it's been claimed she was struggling to pay staff and suppliers.

"Things were left a long time and she spent the past few months struggling to pay the vast amount of her outgoings. It was a tragic situation and she kept it from everyone," a source told the publication.

Mick's daughter with model Jerry Hall, Georgia May Jagger, was also in Australia yesterday, as she was due to walk at Camilla Franks' show as part of Melbourne Fashion Week. She was known to be close to L'Wren and after hearing the news pulled out of the appearance. She is thought to have returned to New York to be with family.

"In light of the recent sad news, Georgia May Jagger will not be participating in Virgin Australia Melbourne Fashion Festival for the Camilla Grand Showcase. We ask that you respect Ms Jagger and her family’s privacy at this very difficult time," Camilla's spokesperson said.

"On behalf of the Festival and the Camilla team we offer our sincere condolences to Ms Jagger and her family."
