Emily MacDonagh posted a small number of snaps on her social media as she celebrated her husbands milestone.
The NHS doctor took to Instagram with two images as they soaked up plush surroundings.
They both enjoyed a relaxing spa weekend at the luxury Champney’s establishment.
Pete beamed as he was pictured in a sleek blazer on top of a crisp white t-shirt, dark trousers and complimentary chelsea boots.
Emily, 34, was rocking a sand coloured wool bodycon dress with knee-high black boots.
The mental health help author captioned the snaps: “We had such a lovely time @champneysspas for Pete’s birthday, feeling thoroughly pampered!!
“Thanks so much to @clairepowellcan for spoiling us ❤️ Happy birthday @peterandre ! ❤️❤️.”
Fans couldn’t help but flood the comments section as they lavished praise on both the stars.
