Mirren, who is the face of L’Oreal’s ‘Age Perfect’ moisturiser range and the oldest celebrity ambassador for the brand, added that she only works with the brand in a capacity that makes her feel comfortable.

“I’ve always said to L’Oreal as well that I will only do what makes me feel better,” she said.

She also spoke about the need for brands to represent a more diverse range of women in their ads, especially when it comes to older women.

“It used to drive me crazy that the ads promoting skin products were using pictures of 15- and 16-year-old girls,” she said.

“As a 30-year-old, I used to look at that and think, what the f**k are you talking about? It was ridiculous. P***ed me off majorly.

“Advertisers are only just coming out of that, and it’s taken them a long time,” she added.

Dame Mirren, we couldn’t agree more.
