Breaking News: Kate Middleton get mad at Prince William for Attending Taylor Swift’s London ‘Eras’ Concert with kids…see more

Anyway, while Taylor performed at Wembley Stadium, which seats 90,000 … there incredibly hasn’t been any footage of William and the kids that’s surfaced (at least not yet) — which suggests they were trying to keep a low profile, probably in a super private box somewhere.

By the way, William’s been a Swiftie for some time. the Prince of Wales and Swift took the stage alongside Jon Bon Jovi back in November 2013 at the Centrepoint Gala Dinner at Kensington Palace in London where they belted out “Livin’ on a Prayer.”

The royal family also posted a two-minute-long video of the guards playing an orchestral version of Swift’s hit, “Shake It Off.”

“Can’t stop, won’t stop groovin,'” the royal family captioned the tweet alongside three emojis: a saluting face, drum and trumpet.

They also tagged the British Army, the Army in London and the Royal Corps of Army Music.
