Taylor Swift’s Eras Tour really is bringing the people together, including some of the biggest names in Hollywood.

Tom Cruise was spotted by fans in the VIP tent at Swift’s second London stop on Saturday night, singing and dancing along to her hit "Shake It Off."

One fan even showed video of herself on TikTok sharing friendship bracelets, a hallmark of the Swift fan experience, with the "Mission: Impossible" star.

Another clip shared on X captured not only Cruise, but Ashton Kutcher and Mila Kunis, and "Barbie" director Greta Gerwig all bopping along to the music.

Also in attendance was Swift’s boyfriend Travis Kelce, happily vibing to her music. His brother Jason Kelce and sister-in-law Kylie Kelce were there as well.

Swift gave a nod to Kelce in the crowd, once again changing the lyrics to her song "Karma" to sing, "Karma is the guy on the Chiefs, coming straight home to me." She did the same during a stop in Argentina when Kelce was in the crowd.
