It seems that Travis Kelce’s onstage moment at the Eras Tour was kept top secret — even from Taylor Swift’s parents!

At the third night in London of the superstar’s record-breaking tour, the Kansas City Chiefs tight end surprised the nearly 90,000 fans in attendance when he joined Swift’s background dancers at the beginning of “I Can Do It with a Broken Heart” — similarly dressed in a suave tuxedo and top hat.

During his appearance, Kelce, 34, carried his girlfriend Swift, also 34, across the stage, gave her faux touch-ups as she switched her outfit, and even treated Wembley Stadium crowd to a few of his signature dance moves.

After Kelce left the stage, eagle-eyed fans captured video of the football star returning to the VIP tent, where he had sung and danced throughout the earlier parts of the show.

As he re-entered the star-studded VIP section, he was showered with cheers and applause — including from Swift’s mom Andrea, 66, who was one of the first to greet him, which she did with a smile from ear to ear. Seen in a video posted to TikTok, Kelce made his rounds through the tent as someone could be heard shouting, “You nailed it, Travis.”

But it seems that Swift’s dad Scott, 72, may have been just as shocked as the rest of the Wembley crowd when Kelce briefly joined the ranks of his girlfriend’s background dancers. Seen in a video posted to X (formerly Twitter), royals, who posed in a cute selfie with Kelce and Swift backstage.
