Jessica BielJessica Biel has revealed she’s started to feel the effects of ageing - at just 26.

She told Marie Claire recently: “I feel my knees changing - like, why do I have this pain when I’m running on the treadmill? What’s going on with my lower back when I wake up in the morning? I just feel changes.

“And I’m definitely fearful in a very vain manner about my body aging.

“I think it’s freaky weird to look at a picture of your grandmother when she was a young woman and look at her now.”

But that’s not to say she’s going to step under the surgeon’s knife to stop it happening: “I am really afraid of blades on my face. That freaks me out beyond belief. I would way rather have wrinkles than have some slice-up going on.”
