Elle Macpherson goes into "model mode" when she is around cameras.
The Australian supermodel admits she tried to take a back seat to the contestants when fronting UK TV show 'Britain's Next Top Model' but struggled to keep her vanity in check.
She said: "I'm a neutral mentor because I believe the show should be about the girls and no one else.
"The thing I found most difficult was when there were six or seven cameras around and I automatically go into model mode.
"Yet I shouldn't be worried about what I look like - I really have to worry about what the girls look like."
The 47-year-old beauty also revealed she believes the secret to looking stylish is being comfortable with yourself.
She explained: "Coco Chanel once said that unless you are comfortable you are not stylish.
"Being completely comfortable in what you wear and who you are, that is true style."
