The 22-year-old model - the daughter of the designer's partner Sir Mick Jagger and his ex-wife Jerry Hall - was set to appear on the runway for Camilla Franks this week, but after being informed of yesterday's (17.03.14) tragedy when she landed in Sydney to take a connecting flight to Melbourne, she axed the catwalk show and has now flown out of Australia back to New York to be with her family.
Camilla's spokesman said in a statement: ''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.
''On behalf of the Festival and the Camilla team we offer our sincere condolences to Ms. Jagger and her family.''
Georgia was close to L'Wren - who was found hanged at her New York apartment - and the two women were regularly seen out and about together, including in September, when she joined her rocker father at L'Wren's London Fashion Week show.
The model's decision comes after Mick's band the Rolling Stones cancelled the first date of their Australian tour following the tragedy.
The band were due to perform in Perth (19.03.14) tomorrow, but the show will no longer go ahead, while the future of the other five gigs in the country is also uncertain.
Many ticket-holders couldn't get into the O2 Arena show on Tuesday night (September 19th) because they didn't bring photo ID to match their booking.
An album re-release, a new song and a documentary mark the singer's legacy this year.
The actor plays the titular hero in the forthcoming adaptation.
