Dame Helen Mirren wears a plunging neckline as she encourages women to reveal more of themselves.

The glamorous 71-year-old actress , star of Prime Suspect and The Queen, says in a skincare advert for L’Oreal: “Why should your skincare stop at your face?

"Tone, tighten, unbutton.”

Whatever would Her Majesty say?

Dame Helen launched a new partnership with L’Oréal Paris last month.

She unveiled a three-year All Worth It programme.

It will offer up to 10,000 young adults across the UK confidence training in 18 dedicated centres and via a digital learning platform.

Dame Helen Mirren doesn't believe she is ‘sexy’ and argues she’s not a 'sexual object'

Dame Helen said: "Overcoming self-doubt is a journey and I am truly happy to see L’Oréal Paris partnering with The Prince’s Trust to help many young people who don’t believe in themselves.

"We have a responsibility towards this generation to lead by example in what we say, how we act, and what we do. I wholeheartedly support this initiative."
