The 73-year-old, most known for her role as Patsy in Ab Fab, called Her Majesty an inspiration due to her sustainable way of living. Ms Lumley told Good Housekeeping: “People say ‘You must need new things’. But when you go to stay at Buckingham Palace - guess what?
“You eat off second hand knives and forks, the bed you sleep in is second hand, the bed linen is second hand – and that’s Buckingham Palace.
“So if it’s good enough for the Queen, treasures, it’s good enough for me.”
She also shared other tips on sustainable living during the interview.
This included refusing washed out bottles and “wearing everything 120 times”.
The Queen has been praised for being thrifty
She said: “I come from an age where you tend to reuse, you make do and mend.”
Royal author Adam Helliker, also revealed the Queen recycled old bedsheets to use them at her holiday home Balmoral Castle.
The sheets came from the Royal Yacht Britannia when it was decommissioned in 1997.
He told Fabulous Digital: “In a materialistic world, how heartening to learn that the Queen continues to espouse frugalness in her royal households.
“Her Majesty is continuing to get good use from the bedspreads she rescued from the former Royal Yacht Britannia when the ship was decommissioned in 1997.”
A royal insider added: “The Britannia bedspreads were salvaged to be used in all the main bedrooms at Balmoral.”
Once they become too worn, the sheets are then reportedly made into cushion covers.
The insider said: “They’ve lasted really well but the Queen has ordered that any which get too moth-eaten are cut up and made into cushion covers.”
The Queen is thrifty in other ways, according to the Sun Online.
String from parcels gets reused, while lightbulbs of more than 40 watts are said to be banned.
Old newspapers are also shredded and made into bedding for the horses.
She travelled to her Christmas break in Norfolk last year on a public train, with her ticket thought to have cost around £50.

Phil Dampier, co-author of What’s In The Queen’s Handbag And Other Royal Secrets, added the Queen always “watches the pennies”.
He said: “Very often when she’s at home she’ll be happy to have leftovers.
“She is careful with money and always watches the pennies.
“She has got handbags which she has had for 30 or 40 years and which she continues to use.”
