It has become one of the streaming service’s most successful seasons of TV ever, with fans watching in their millions.
One eagle-eyed viewer, TikTok user @txharvey, watched the series so intently that they spotted an image that shares a likness with the prime minister tucked away in the background.
The background detail can be seen in a scene featuing Kate as she is struggling to sleep. The user uploaded a clip to TikTok, which has now been watched more than one million times.
One fan wrote: “I’d love to know who the set designer was that snuck this in,” whereas one other added: “No wonder she couldn’t fall asleep.”
One other fan recommended that they had observed it themselves, stating: “I thought I was going insane when I saw that in the show.”
Bridgerton is on the market to stream on Netflix.
