US singer-songwriter Taylor Swift performs onstage on the first night of her "Eras Tour" at AT&T Stadium in Arlington, Texas, on March 31, 2023.

A month after Beyoncé's attendance at Taylor Swift's "The Eras Tour" concert film premiere, Swift reciprocated the support by gracing the "Renaissance" film premiere in London.

On Thursday, the 12-time Grammy Award winner walked the red carpet of the "Renaissance: A Film by Beyoncé" premiere in a dazzling sleeveless silver Balmain dress. The floor-length gown, adorned with sequins all over, featured a thigh-high side slit that added a hint of allure to her ensemble.

The "Anti-Hero" singer also sported her classic red lip, with her wavy hair styled in a chic side part. She accessorized her outfit with silver drop earrings and gleaming rings.

To complete the look, Swift had on shimmering silver nails. She opted for a pair of open-toe black heels, allowing her red-painted nails to peek through.

The "Bejeweled" singer flew over 4,300 miles from Kansas City, Missouri, where her boyfriend Travis Kelce resides, to London to show her support for Beyoncé, according to Elle magazine.

In October, Beyoncé made an appearance at the Los Angeles premiere of the "Eras Tour" concert film clad in a sleek, body-hugging black suit accentuated by an eye-catching metallic silver breastplate.

Swift expressed her gratitude for the presence of the "Cuff It" singer by sharing on Instagram a boomerang photo of the two of them seated in the theater, accompanied by a heartwarming caption.

"I'm so glad I'll never know what my life would've been like without @Beyoncé's influence. The way she's taught me and every artist out here to break rules and defy industry norms," the "Cruel Summer" singer captioned. "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 [smiling face with halo emoji] [folded hands emoji] [face holding back tears emoji]."

The global theatrical release of the "Eras Tour" concert film commenced on Oct. 13, marking the biggest debut for a concert film of all time. It soared to unprecedented heights, raking in $92.8 million domestically during its opening weekend alone, according to People.

Meanwhile, "Renaissance: A Film by Beyoncé" is scheduled to hit theaters worldwide Friday. It is expected to bring in $17 million to $20 million in its first weekend, according to Variety.

Swift and Beyoncé's tours dominated Forbes' highest-grossing concert tours list of 2023.
