Dame Joan Collins still buys her own groceries from the supermarket

In an interview on BBC Radio Two, Joan said: "After this I'm going to a supermarket and then to a department store to buy some bits and pieces."

When asked which supermarket she shops at, she replied: "It beings with a 'W' (Waitrose). I've been there too (Lidl), and we were visiting some friends recently and we went to Sainsbury's."

Though Joan sometimes gets recognised on her shopping trips, she insists people simply "don't care" when they spot her.

She added: "I'm not clocked everywhere I go, for example in our local shops and where we live locally I go out I've got maybe a baseball cap on and a raincoat and people don't take any notice. They might say, 'Oh, it's Joan Collins' but there's no big deal - it's not like I'm Brad Pitt or Leonardo Di Caprio. People don't care.

"I've been around a long time so they take me for granted. Cab drivers always recognise me."

Speaking about her upcoming film role in 'The Time of their Lives', Joan hopes people will like it, even though there is no "blood, sex or violence".

She said: "I hope people love it because it hasn't got blood, sex, violence and guns and gore and swearing however I do use the F-word twice and the S-word once."

And the former 'Dynasty' star - who married fifth husband Percy Gibson in 2002 - claimed the secret to looking fabulous at her age is living life to the full.

She added: "Maintenance, keeping out of the sun, eating good food, very positive attitude towards life. When life gives you lemons, which in my case it has a lot, then you have to make lemonade and I think I squeezed the most out of life and living life to the full is also a gift."
