Princess Charlotte stole her show with her “fiery” attitude backstage following Taylor Swift’s concert in London.

Princess Charlotte seems to have captivated Taylor Swift’s boyfriend, Travis Kelce and his brother, Jason, during their meeting backstage after the superstar’s concert in London last week.

The Prince of Wales had a special way of celebrating his 42nd birthday last Friday, as he attended the singer’s hugely anticipated Eras Tour concert at Wembley Stadium with his two eldest children, Prince George, 10, and Princess Charlotte, 9.

Prince William’s “dad-dancing” skills went viral on social media after he was caught on video “shaking it off” to Taylor Swift’s homonymous song. But it was his selfie backstage with the singer herself and his children that stole the show.

After Kensington Palace posted a selfie from backstage, showing Taylor crouching next to the royals and taking a photo on her phone, the singer posted her snap on social media, wishing the heir to the throne a happy birthday.

The image featured Taylor, William, George and Charlotte, as well as the singer’s boyfriend, NFL star Travis Kelce.

And it looks like his brother, Jason, who was also at the concert, was in the special royal meeting backstage too.

Talking on their podcast, New Heights with Jason and Travis Kelce, Jason talked about how Charlotte made the biggest impression on him, explaining: “I gotta say, Prince William was fantastic when I met him, but the highlight was Princess Charlotte.

“She was so f****** adorable. I don’t know, maybe it’s because I have three girls now.

“She had fire to her, she was asking questions.”

Elsewhere, Travis labelled William the “coolest” after their meeting.

“He was awesome. He was so cool. I didn’t realise this as obviously we were backstage meeting him because he was there with little George and Charlotte, and they were an absolute delight to meet.

“Wasn’t sure if I was supposed to like bow to them, curtsy, just be an American idiot and shake their hand.”
