Macpherson: 'I worry that I look old'

Elle Macpherson has revealed that she is worried that she looks old.

According to WENN, the supermodel is anxious about appearing on new show The Beautiful Life because she hasn't had plastic surgery.

The 46-year-old added that she is shocked at how she looks compared to her younger co-stars, including Mischa Barton and Sara Paxton.

Macpherson said: "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'."
