Poinbank Exchange|Taylor Swift Reacts to Beyoncé's "Fairytale" Appearance at Star-Studded Eras Tour Film Premiere

When Beyoncé walked in the room,Poinbank Exchange the whole place shimmered. 

The much-anticipated film version of Taylor Swift's Eras Tour had its Hollywood premiere on Oct. 11, and it is safe to say many of her celeb pals were ready for an enchanted evening out, including Queen Bey.

"I'm so glad I'll never know what my life would've been like without @beyonce‘s influence," Taylor wrote on Instagram after the event. "The way she's taught me and every artist out here to break rules and defy industry norms. Her generosity of spirit. Her resilience and versatility. She's been a guiding light throughout my career and the fact that she showed up tonight was like an actual fairytale."

In fact, Maren Morris, Adam Sandler, Simu Liu and Allison Hsu, Flavor Flav, Mariska Hargitay and daughter Amaya Hermann were among those who stepped out at The Grove in Los Angeles to support the "Karma" singer.

As for the woman of the hour, Taylor subverted her self-proclaimed anti-hero identity and looked every bit the leading lady, donning a gorgeous blue Oscar de la Renta gown for the occasion.

Just as August slipped away like a bottle of wine and the first leg of her Eras Tour came to a close, the "Cruel Summer" singer revealed she was releasing a film version of her ultra-popular concert, allowing for fans who weren't able to score the highly coveted tickets a chance to experience the show for themselves. 

"The Eras Tour has been the most meaningful, electric experience of my life so far and I'm overjoyed to tell you that it'll be coming to the big screen soon," Taylor captioned an Aug. 31 Instagram post. "Starting Oct 13th you'll be able to experience the concert film in theaters in North America! Tickets are on sale now at amctheatres.com. Eras attire, friendship bracelets, singing and dancing encouraged."

Notably absent for the event was Taylor's rumored new boyfriend Travis Kelce, whose team the Kansas City Chiefs is preparing for its game against the Denver Broncos on Oct. 12. The tight end, who saw support from the Grammy winner at two recent games, ultimately sat out the star-studded affair. However, luckily he was able to catch Taylor's Eras Tour stop in Kansas City back in July.
