In a surprising turn of events, Kate Middleton was noticeably absent from Friday's Eras Tour concert in London. Instead, Prince William was seen shaking it off alongside their two oldest children, Princess Charlotte and Prince George. The event, headlined by Grammy-winning singer Taylor Swift, attracted a star-studded crowd at Wembley Stadium.

The reason for Kate's absence was revealed that she stayed home with their youngest child, 6-year-old Prince Louis. It was reported that Kate, who recently made her public debut following a cancer diagnosis, will not be attending any future Taylor Swift concerts. An unnamed source clarified, "Her appearance at the King's Trooping the Colour doesn't mean she is returning to a full schedule of public engagements yet."

The royal family's support for Taylor Swift was evident as Prince William shared a selfie of himself, Princess Charlotte, and Prince George along with the pop star. They expressed their gratitude to Taylor Swift in the caption, "Thank you @taylorswift for a great evening! #LondonTSTheErastour." It should be noted that the photo was taken prior to the concert.

Not to be outdone, Taylor Swift also took to social media to post a selfie with the royals and her boyfriend, Travis Kelce. She wished a happy birthday to Prince William in the caption and expressed her excitement for their London shows, which marked her and Kelce's first Instagram grid moment.

During the concert, Prince William couldn't contain his enthusiasm as he was seen bopping along to Taylor Swift's hit song "Shake It Off." This is not the first time the prince has shown his admiration for the singer, as they previously shared the stage with Jon Bon Jovi at a gala dinner in Kensington Palace back in 2013.

The Eras Tour in London has attracted a slew of celebrities, further adding to its star power. Ashton Kutcher, Mila Kunis, Tom Cruise, Jason Kelce, Kylie Kelce, and Hugh Grant were among the notable names spotted in the audience.

While Kate Middleton's absence from the concert was unexpected, her focus remains on her recovery and family. Fans will eagerly await her return to public engagements in the future.
