Taylor Swift's Many Celebrity Fans Revealed

Taylor Swift's The Eras Tour is breaking records left, right and center, so it's no surprise some of the biggest names in show business want to check it out.

Swift, 33, has been on the road since March with her 44-song set list show which is broken down into 10 acts and showcases different eras in her career.

It is on track to become the highest earning live music tour of all time and even managed to break Ticketmaster when 2 million people logged in on the first day tickets went on sale, more than any other artist in history.

The Eras Tour has attracted so much attention that it seemingly even managed to repair the rift between Swift and former BFF, Karlie Kloss, who attended the final show in Los Angeles this week.

But Kloss was not the only big name who made sure to catch Swift live, as the singer has attracted some mega celebrities to her show.

Some were too cool to post their attendance to social media, including Blake Lively, Ethan Hawke, Adam Sandler and Emma Stone, but were spotted by eagle eyed-fans.

But others shared their excitement to Instagram including Kerry Washington, Amanda Kloots, Jeff Goldblum, Halsey, Sydney Sweeney, Cameron Diaz, Tiffany Haddish and Zoe Saldana.

Oscar winner Charlize Theron was also spotted in the VIP tent at one of the shows, while Sophia Bush also attended, as did Jessica Alba, Sofia Vergara and music producer Diplo.

Vanessa Bryant, the wife of late NBA star Kobe Bryant, attended a show with her daughters, with 6-year-old Bianka being gifted the "22" hat while Swift performed the song of the same name.

Transgender influencer Dylan Mulvaney posted pics from one of the L.A. shows and How I Met Your Mother's Alyson Hannigan also saw Swift live.

Country star Shania Twain also attended, with some hoping she might even appear onstage alongside Swift.

Some musicians who did play live with Swift on the tour included Marcus Mumford and HAIM.
