Taylor Swift made headlines as she took her romance with Travis Kelce to the next level during her London Eras Tour. After a sold-out performance at Wembley Stadium, Swift celebrated by going Instagram official with the Kansas City Chiefs player. Kelce attended the show with his brother Jason and sister-in-law Kylie.

The Instagram debut was not just any ordinary post—it featured Swift, Kelce, and three royal cameos. Prince William, celebrating his 42nd birthday at the concert, and his children Princess Charlotte and Prince George joined Swift backstage for a memorable selfie. They also took another photo with Kelce, who sported a USA Olympics baseball cap and an olive green shirt, while Swift dazzled in her signature red lip and a sparkly black pinstripe blazer.

The moment was a blend of American and British royalty, akin to Taylor’s self-proclaimed status as an “American queen” in her song “King of My Heart.” Swift’s Instagram caption, “Happy Bday M8! London shows are off to a splendid start,” referenced Prince William’s birthday and marked the official debut of her relationship with Kelce.

During her performance, Swift also gave a nod to Kelce by mimicking his touchdown celebration—a move he famously does for the Kansas City Chiefs—while singing “So High School,” believed to be inspired by their relationship.

With Taylor Swift’s bold move to hard-launch their relationship, all eyes are now on Travis Kelce to see if he follows suit in sharing their romance publicly.
