It’s…Simon, the son of David and Shirley Griffiths!

The proud parents posted the loving photo as he completed the half marathon in Cardiff.

More recently, Dave and Shirley posted videos of him running in the race, cheering him on in the background.

It comes after Gogglebox fans burst into laughter after seeing Shirley’s hilarious response to a very awkward question from her husband Dave about his actions in the bedroom during a recent episode.

The couple, who live in Caerphilly, Wales, briefly discussed their romantic lives while watching model Cara Delevingne’s BBC documentary Planet Sex.

But Shirley quickly ended the conversation when Dave grilled her when he asked about their sex life: “You’re not disappointed, are you?”

As part of Cara’s documentary, she investigated the difference in satisfaction between men and women in bed.

After admitting that some women acted like they were having a good time, Dave turned to his wife for some reassurance and asked confidently, “You’ve never been let down, have you?”

But he seemed stunned when Shirley uttered no words before simply bursting into laughter.

Dave further urged her to get an honest answer, saying, “Come on… speak honestly.”

But as she continued to laugh, she refused to give in and said, “Look, let’s watch the show.”

Fans of the show took to Twitter to laugh at the moment.

One person wrote: ‘Shirley’s reaction at the time was EVERYTHING. That’s what EVERY woman does when a man she likes questions her.’

Another viewer wrote: ‘Fantastic ending to #Gogglebox. Poor Dave didn’t know what was going on.’

“Shirley is killing me with her comments,” another fan wrote, while someone else tweeted: “Just call him Shirley!”

Another viewer simply commented: “Shirley speaks her truth!”
