The reason Kate Middleton did not go with Prince William and her children to the Taylor Swift concert in London.

The Princess of Wales has spent most of 2024 getting treatment for cancer.

Kate Middelton could not go to the Eras Tour with her husband and their kids because she was minding Prince Louis in a situation unrelated to her cancer treatment, according to a royal expert.

The Princess of Wales was stunned in January when she was told she had an undiagnosed form of cancer after undergoing unconnected abdominal surgery at The London Clinic, around the same time King Charles III received his own news of cancer.

As a result, she withdrew from the public eye sparking a lot of conspiracy theories before March’s emotional revelation of the news. Thankfully, she seems to be doing okay and is slowly returning to public duties although she couldn’t head to see Taylor Swift for other reasons.

“I think [it was] sensible in the case of Louis because I think he’s unpredictable at the moment, given his age,” ex-Royal Correspondent, Charles Rae, said to The Sun.

“I can understand why Catherine didn’t go.

“She’s still recovering and I think she’s, rightly so, pacing herself at the moment. We saw her at Trooping the Colour, which was fantastic, she looked absolutely sensational. It was nice to see her back again.

“But I think it was the right decision that those two stayed away, I’m sure Louis didn’t miss out too much.”

Eras Tour selfie a turning point in Royal Family relations.

Prince William took Prince George and Princess Charlotte to Wembley Stadium in late June to watch the American popstar ace perform on stage, but they even managed to go one better by snapping a selfie with Swift and her NFL boyfriend, Travis Kelce.
