Prince Charles, Camilla, Geri Halliwell

Prince Charlesneeds to spice up his life, if you ask his wifeCamilla.

The Duchess of Cornwall spilled the tea toGeri Halliwell, calling the future king a “complete workaholic” during a friendly chat on Thursday.

After a friendly hug and a kiss on the cheek, the women exchange quiet pleasantries, with Camilla dryly confiding that her husband, 72, is keeping busier than she would like.

But for the singer, actress and author formerly known as Ginger Spice, that may be a good idea.

“I read this book,” says Halliwell, 49, “and they say the key to living a long life is carry on working — don’t retire, that’s the key.”

Charles' work surely won’t let up any time soon — particularly when it comes to his decades-long fight for the planet. Next week he and Camilla, 74, will attend the COP26 United Nations Climate Change Conference in Glasgow alongsidePrince WilliamandKate Middleton, both 39.

William heads to the meeting of world leaders in Scotland fresh off hisinaugural Earthshot Prize ceremonyon October 17.

“The urgency of the [climate crisis] can’t be overstated, but through the Earthshot Prize, I want to show people across the world why there is reason to be hopeful,” he told PEOPLE exclusively after awarding five prizes of $1.3 million to advance their efforts to repair the planet over the next decade.
