While the rest of us bemoan the end of the British summer, the couple haven't been complaining about the rain, instead they've gone away to one of their special places.
Fiona captioned the gallery of pics: "Gorgeous few days with my [heart emoji] in one of our favourite places, beautiful Deia."
Fiona's followers were quick to comment, with most saying how lucky Simon is to have her!
"Lucky man, beautiful lady," wrote one.
"He is so lucky to have someone so beautiful in his arms," added another.
A third said: "Stunning as always Fiona, you look so happy."

Fiona and Simon got engaged at New Year and revealed their plans to marry in October.
In an interview with OK! magazine, she said:"We've just started looking at venues.
"We need to move quickly as we're hoping to get married in October. I don't see the point in waiting around, and in my faith people get married quite quickly."
The actress also told how she was in "floods of tears" when Simon proposed to her at her family home in Hertfordshire.
"The proposal was perfect. It's the home I grew up in and I still live there with my mum when I'm not filming. It's the most special place in the world to me."
Simon briefly appeared in Emmerdale alongside Fiona in August 2017 when he played Home Farm Estate client Hugh Bryant.
His scenes were with Rebecca White, but Hugh ended up terminating his business contract with Home Farm after his car was set on fire.
