And some fans thought he had shared a bit too much when he posted a video clip of him playing football in the garden.
Fans of the celeb dad hilariously thought that the other person in the video was Rio’s fiancée, and they thought she was playing football – topless!
One said: ‘I need glasses. I thought it was Katie, topless and I was like wtf 🤦🏻♀️🙊’.
Another added: ‘wasnt just you. Was me Too. Had to read the caption to find out who it was 😂’.
But despite the initial mix-up, they soon discovered that it was actually Rio’s son spending some quality time with his father.
Alongside the video, the dad-of-three wrote: ‘#fatherandson keepy uppys- upstairs downstairs!! Lovely touch with the big toe!!#football #soccer #skills’.
Rio’s children rarely make an appearance on his dad’s social media accounts – as Rio likes to keep their lives as private as possible – so this is why perhaps some fans didn’t instantly clock that it wasn’t Kate in the video.
The pair are due to marry very soon, as the former reality TV star has already travelled to Greece for a fun-filled hen do with her best pals.
She also recently made a very exciting announcement, as she revealed she will making a debut as an author and publishing a book on how she manages to stay healthy and in shape, called Fitter, Happier, Healthier.
Alongside a picture of the book’s cover, she wrote on Instagram: ‘Exciting news 🙊🤗🥰 I’m so excited to finally tell you all about my first ever book… 📖
