Backstreet Boys' AJ McLean has extended an invitation to Taylor Swift to perform with the iconic boy band during their Las Vegas residency at the Sphere. The invitation follows a viral mashup of Swift's "Elizabeth Taylor" and the Backstreet Boys' "Everybody (Backstreet's Back)", created by Lydia Getachew, which gained traction after McLean shared it on his Instagram.

McLean revealed his desire for a collaboration while speaking with TMZ about potential guest performers for their "Into the Millennium" residency at the Sphere. He mentioned other artists he'd like to share the stage with, including Coldplay, Lenny Kravitz, and the Red Hot Chili Peppers, but emphasized that Swift was his top choice.

McLean expressed his admiration for Swift, describing her as "the sweetest" and "the best," and noted her kindness towards his daughters when they've met her at her shows. He also acknowledged that Swift is a fan of the Backstreet Boys, and the band members are huge fans of her. This mutual admiration could set the stage for an unforgettable performance.

The mashup of "Elizabeth Taylor" and "Everybody (Backstreet's Back)" has garnered over one million views on TikTok, and McLean believes that a live collaboration would "break the planet". He playfully suggested that Swift should come see the show first to get a feel for it, and then decide if she wants to join them on stage, adding, "We're not going to say no".

The Backstreet Boys have announced new Las Vegas residency dates for December 2025 and January 2026, providing a window for a potential guest appearance. The residency takes place at the Sphere, a state-of-the-art venue that opened in late 2023. The venue boasts an immersive experience, with 580,000 square feet of LEDs behind, above, and around the artists on stage. McLean teased that the group is "taking Sphere to the next level" and that they've been given the go-ahead to try things that have never been tried in the venue before.

Following McLean's Instagram post of himself enjoying the viral mashup, Swift commented, "OH HI AJ OH MY GOD," fueling fan excitement about a potential collaboration. Fans have taken to social media to express their hope for Swift to appear as a surprise guest, using hashtags like #SwiftStreetCollab and #BackstreetSphere.

As of November 12, 2025, Taylor Swift has not publicly responded to McLean's invitation. The world awaits her decision, as a collaboration between these two pop culture icons would undoubtedly be a historic musical event.
