Penny Lancaster once "tried" Botox without telling her husband Sir Rod Stewart

Asked how she is "coping" with the ageing process while being in the public eye, Penny told the new issue of Woman magazine: "I'm quite self-conscious about the weight I've put on, and I wonder who is this older woman I'm seeing now, especially when I look at my phone and the camera comes on!

"I tried Botox just before I got married. And it worked. But I hadn't told Rod, and he noticed.

"He said, 'Your whole expression has changed.'"

But because Botox never gave Penny the result she wanted, the blonde beauty stopped having it.

Penny continued: "I thought I'd still try it because it was about making me happy, but it was never the result I wanted, so I gave up on it."

In 2017, the star revealed that Rod persuaded her not to have cosmetic surgery and to embrace her natural beauty after breastfeeding their two sons - Aiden, 19, and 14 year old Alastair - caused her to have insecurities.

Appearing on the UK lunchtime talk show Loose Women that year, Penny explained: "They did this camera sweep around my body and said, 'This is what your boobs would look like if you did this or that.'

"And then he said to me, 'I have one really important question. Are you happy with the rest of your body?'

"And I said, 'Well, I'd probably want to lose a few more pounds here and there.' And then he said, 'Well, go away and do that because if you start on one thing, you'll want another.'

She continued: "I was seriously thinking about getting them done, but Rod said, 'Look, darling, if you decide to do that to your body, then I'd support you, but I love them the way they are.'"
