Elle Macpherson is an inspiration to her, but model Jennifer Hawkins doesn't think she'll have the same runway stamina as The Body.

Hawkins, who starred at the Myer autumn/winter 2010 launch at the Sidney Myer Music Bowl on Monday night as part of Melbourne Fashion Week, said the supermodel's shock catwalk appearance at the Louis Vuitton show in Paris earlier this month was nothing short of amazing.

"She looked fabulous!" cried Hawkins when asked about Macpherson's latest turn on the runway.

"I didn't expect it at all. She looks good and it shows it's not just about a certain age and size anymore. Elle is almost 50 and looks fantastic.

"She's always been an inspiration and not just for modelling, but because she has a go at everything from fashion, to movies, television, her lingerie line and she's a businesswoman."

Macpherson, who has just became the host and executive producer of Britain's Next Top Model, has been named by Forbes magazine as one of the world's highest earning supermodels.

Hawkins, 26, is following in Macpherson's trail-blazing success as the multi-million dollar face and body of the swimwear label Cozi by Jennifer Hawkins, Covergirl, Lovable, Audi and Myer.

But as for lasting the runway distance that Macpherson has achieved, Hawkins believes she will have well and truly hung up her heels by the same age.

"Probably at 46 I would hope I have my own business and a family and be hopefully happy, but who knows."
