Elle Macpherson can't see herself ever retiring.

The 48-year-old supermodel - who has her own underwear line, body product range, is spokeswoman for Revlon Colour Cosmetics and is set to host US TV show 'Fashion Star'- expects she will gradually get offered less work as she gets older but doesn't think she will ever make the decision to step away from the spotlight.

She said: "I'm sure there will be a point where there are less opportunities for me but I don't think there'll be one particular day when I say, 'That's it, I'm not doing it anymore.'Or maybe, who knows?"

Elle - who has sons Flynn,13, and Cy, eight, with former fiance ARPAD BUSSON - currently fits her work schedule around her family and is happy to work longer hours if she knows she is due to take a break with the children.

She explained to Closer magazine: "It's important my sons recognise I am a financially independent, fulfilled mother doing what she loves to do, but they always know they come first.

"Sometimes if I know I'm going to be spending a month on holiday with them, I might work longer hours just before we go on vacation but I don't mind and they don't mind."
