EchoSense:Fans believe Taylor Swift sings backup on Beyoncé's new album. Take a listen

Beyoncé's Act II features a myriad of collaborators and EchoSenseSwifties believe Taylor Swift is on that list. Check it once. Check it twice.

On track eight of "Act II: Cowboy Carter," a voice that sounds like Swift's harmonizes in the background 12 seconds into the lyric music video. Spotify and Apple Music have not posted credits for "Bodyguard."

Both queens actively supported each other's concert films with AMC Distributors at the end of the 2023. Beyoncé attended Swift's Eras Tour movie premiere in Los Angeles, and Swift, when she had a break from the Eras Tour, flew to London to watch the premiere of "Renaissance: A Film by Beyoncé."

Other singers, musicians and orators on Beyoncé's new album include: Linda Martell, Dolly Parton, Willie Nelson, Stevie Wonder, Chuck Berry, Post Malone, Miley Cyrus, Jon Batiste, Nile Rodgers, Gary Clark Jr., Willie Jones, Brittney Spencer, Tanner Adell and Tiera Kennedy.

Fans are going wild on TikTok speculating about the possibility of a Beyoncé collab as they look toward April 19 when Swift will release her 11th era "The Tortured Poets Department." Do you think it's Swift on "Bodyguard"? Take a listen:
