Hurley and Collins Shine at Film Premiere

and showed some of showbiz's rising stars how it's done as they posed for snaps together at the premiere of A Murder Between Friends.

No stranger to red carpets, the pair put on a glamorous display as they posed for snaps together at the Curzon Mayfair.

Elizabeth, 60, showed off her famous figure in a low-cut red dress as she supported Joan in her latest role in the murder mystery satire.

The actress was supported by her son Damian, 24, as they attended the premiere together, along with guests including and Tamara Beckwith.

Joan, 93, showed off her age-defying appearance in a sophisticated black dress adorned with intricate gold sequins, as she arrived alongside her husband of 24 years Percy Gibson.

The Dynasty legend plays an iconic TV star in the film, no doubt a nod to her own acting roots, who tries to solve a murder mystery at her country estate. 

Joan has previously stunned fans by looking far younger than her years, and in a recent interview she shared how she's maintained her incredibly youthful looks for 45 years, since she shot to international fame as the scheming Alexis Colby in Dynasty.

The acting legend opened up about what she does to continue looking so fresh and youthful, sharing her belief that 'taking care of yourself is one of the most important things'.

However, those hoping to learn all the tips and tricks they can use to emulate the glamorous nonagenarian will be disappointed to learn that Joan credits her longevity to the favourable genetics she inherited from her parents.

'I have very good genes – I'm very lucky,' the actress admitted to The Telegraph. 'My father lived to be 87, and for somebody born in 1903 that's pretty amazing.

'My mother took incredibly exceptional care of me and my sister. When we were growing up she gave us all supplements when nobody was taking supplements.'

While she insists she doesn't follow any fad diets or regimented health routines to keep fighting fit, saying: 'I just believe in healthy living. I don't eat junk, I get eight hours of sleep, I exercise. It's very simple.'

Even when it comes to her mental wellbeing, Joan said that she's simply never had any reason to think about it as she has 'perfect' mental health, thanks to her happy childhood, lack of substance abuse and prioritising her loved ones.

'I never have thought about my mental health, ever. My mental health is perfect,' she said. 'I had great parents, I had a wonderful, loving mother, a quite strict father, so I never got into drugs and booze or any of that, so I never thought that there was anything particularly wrong with me. 

'But being healthy is not my main focus. My main focus is my life, my children, my husband, my friends.' 

While Joan is a strong proponent of the mantra that prevention is better than cure and won't hesitate to see a doctor for any minor ailment, 'even if I have a pimple on my face that doesn't go after a couple of months'.

She points out that health and fitness is something you must work to maintain and any bout of serious illness or injury could derail everything, declaring: 'Anybody over the age of 60 who falls is doomed' because 'it keeps you out of the gym, you lose your flexibility, and everything spirals down.'

And it has paid off so far, as she revealed that after being cast as  in upcoming biopic, My Duchess, she underwent a medical test for insurance purposes and proudly relayed: 'They told me I was more healthy than any of the other cast!'

But while plastic surgery has become more and more popular with today's celebrities with the developments of different types of 'tweakments' to maintain their glam looks, Joan has always been resolute in her unwillingness to go under the knife.

'I do not believe in what they call tweakments,' she insisted. 'I've never had them, which is why I look more or less the same as I have done for years.'

In recent years, she has defiantly hit back at accusations that her youthful looks were the result of surgery, insisting she is ageing naturally and that she is 'appalled' by her fellow stars who have indulged.

Refuting plastic surgery speculation to The Sun in 2017, Joan said: 'If people want to think I've had surgery, then… You can tell [I haven't] because I have lines and jowls. 

'When I see women around my age, I think, oh really? My gosh, I look quite a bit... I think I look pretty good!'

While she reiterated in 2023: 'A lot of people think I've had a ton of work done. To set the record straight: I have not.

'I haven't had Botox, I haven't had any tweakments, I haven't had fat injections, and honestly, when I look at the women who have – certainly a lot of women in their 40s – it appalls me.'

Instead, Joan said her age-defying skin was down to her practice of always sleeping on her back and making sure to wear SPF and keep her face out of the sun to prevent damage from UV rays.

However, she does have certain rules when it comes to her skincare routine, previously revealing: 'I don't go to bed without taking off my makeup and putting on night cream. My mother had me and sister Jackie doing that when we were 14.'

When it comes to her fitness and nutrition, she has acknowledged she's had to adapt over the years, saying as you get older you 'cannot put that amount of stress on your body'.

In fact, she had to scale back her movement in recent years due to a trapped nerve, which led to her not being able to function for about two months.

However, with the help of physiotherapy, she has been able to fully recover and enjoys gym workouts and Pilates.
