Taylor Swift brought out the Hollywood celebrity "who's who" on her 2nd "Eras Tour" show in London, giving the rest of the world a serious case of FOMO.

On Saturday, 6/22, dozens of celebrities were found "upset" by Swift's history・making performances, including Tom Cruise, Hugh Grant, Ashton Kutcher, Mila Kunis, Greta Gerwig, Liam Hemsworth and Jamie Dornan.

Of course, Swift's lover Travis Kelce, along with his brother Jason Kelce and his sister・in・law, Kylie Kelce, came back for the 2nd night.

"Dear@taylorswift13, you have an incredible show,excellent if you are a great and v kind team and a huge boyfriend (#tequilashot.Hugh Grant posted on X, formerly known as Twitter, after the show. "Thank you so much from an older boy in London, his wife and excited 8-year-old #halfgirlhalfbracelet.

As many fans have pointed out online, Grant showed up at Wembley Stadium early to watch Paramore's opening set and, to many's surprise, was found eating carrots inside a vip tent.

"I don't know what to say," one fan shared on x, along with a video of Grant enjoying Bugs Bunny.

"Liam Hemsworth is attending N2 at Wembley!In addition to the footage Hemsworth enjoys in the crowd, one of Swift's fan accounts posted on X.

Another Swift fan account posted numerous photos of celebrities attending on Instagram, including snapshots of Cruz exchanging friendship bracelets with fellow Swifties. Additional photos showed Mila Kunis in the VIP tent, Ashton Kutcher, Liam Hemsworth, Greta Gerwig and Rachel Zegler on their way to Wembley for the show.

A video of a party in a VIP tent during the show is online, so to speak, showing how some of Hollywood's most iconic stars come down.

"Every time you watch this video, you see a new person. greta.-gerwig?? tom cruise??!One of the fans posted on X is acting with a video of the VIP party.

"This vip tent looked so much fun," another commented, along with another video of Kelce and his fellow celebrities dancing, swaying and singing along to Swift.

"The VIP tent is like Hermione's magic bag Harry Potter because new celebrities keep showing up and wondering how tf will fit in that tent," another post said, that found the light.

A video shared online showed Kutcher and his son dancing inside Wembley when Swift performed, and 2 more footage of the night showed Travis Kelce dancing with Tom Cruise (a sentence I never thought I'd write) .

"Taylor Swift has a trance to everyone," one X user shared. Tom Cruise, Liam Hemsworth, Hugh Grant, Ashton Kutcher, Mila Kunis, Travis Kelce, Jason & Kylie Kelce are all dancing to 'shake it off'."I've never seen Tom so relaxed.

Only Swift was able to gather a lot of celebrities and make them dance so that no one was watching!
