Queen Elizabeth was supposed to travel to Northern Ireland on October 20, but she ended up staying home instead.
When asked if the Queen is in "good health," royal expert Angela Levin said, "I don't know, I'm sure they wouldn't tell us until it got quite bad. She does look haunched, doesn't she? She looks as though she's bending over a lot more. She is a bit wobbly on her legs and we know it's not [because of] drinking because she's given up alcohol."
Levin continued, "She's very strong, she's stoic. If she's got lots to do she blossoms. It's a good lesson to us all. She takes a lot on board. She's still riding her horse, I think. That's a positive way of living, there's a lot you can take from her. She won't let bad things get her down."
Earlier that day, the palace gave an update on how the 95-year-old is doing.
"The Queen has reluctantly accepted medical advice to rest for the next few days," a note read. "Her Majesty is in good spirits and is disappointed that she will no longer be able to visit Northern Ireland, where she had been due to undertake a series of engagements today and tomorrow. The Queen sends her warmest good wishes to the people of Northern Ireland, and looks forward to visiting in the future."
The Queen has been making a lot of public appearances as of late, and she is set to attend the COP206 UN Climate Change Conference alongside Prince William, Kate Middleton and Prince Charles on October 31.
The news of the Queen's current condition comes one day after she turned down The Oldie magazine's Oldie of the Year award.
"Her Majesty believes you are as old as you feel, as such the Queen does not believe she meets the relevant criteria to be able to accept and hopes you find a more worthy recipient," Tom Laing-Baker, the Queen's assistant private secretary, said in a letter on Tuesday, October 19.
