Supermodel ELLE MACPHERSON fears fans will think she’s starting to look old at 46 when she appears on new U.S. TV show THE BEAUTIFUL LIFE – because she hasn’t had any plastic surgery.

The Aussie stunner admits even she’s shocked at how she looks compared to her beautiful co-stars, like Mischa Barton and Sara Paxton.

Macpherson, who plays a modelling boss, says, “Sometimes I really see that I’m the one that hasn’t done anything because I think, ‘People must think oh my God, she looks old.'”
