Joan Collins and Celia Imrie could be sisters as they twin in white outfits for glam event

Both Joan Collins and Celia Imrie were in attendance at the Casting Directors Luncheon on Friday, and the glam actresses could have been mistaken for sisters during the event.

The pair showed up at the event wearing white outfits, with Joan, 93, opting for a polka-dot blouse alongside a wide-brimmed hat and black dress, while Celia, 73, dressed in a striped white suit for the glam event.

Joan and Celia were seen interacting during the event as they shared a laugh and posed together. Joan was also seen posing with her husband, Percy Gibson, and fellow thespians, including Charles Dance and Marisa Berenson.

Joan’s age-defying looks

Joan, 93, looked like she could easily have been Celia’s twin, despite their 20-year age gap, and the Hollywood starlet has long been famed for being able to hold the years back.

“I just believe in healthy living,” she previously told The Telegraph when asked about how she manages to stay looking so young. “I don’t eat junk, I get eight hours of sleep, I exercise. It’s very simple.”

While many can use Joan’s advice as a starting point for their own wellness journey, one aspect they can’t imitate is her genetics. “I have very good genes – I’m very lucky. My father lived to be 87, and for somebody born in 1903 that’s pretty amazing,” she explained.

She continued: “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.”

The actress also revealed that she took exceptional care when it came to her mental health, sharing: “My mental health is perfect. 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.”

However, one thing that Joan will never do is have plastic surgery. In an exclusive interview with HELLO! in March, she admitted: ” I don’t believe in needles and things. I’ve never had Botox or anything in my face.”

She also stated that “if you feel good, you look good”, revealing that she exercises up to four times a week. “I think it’s important, but it’s not terribly strenuous anymore. You don’t get legs like this if you don’t!”
