AJ McLean Says Taylor Swift Backstreet Boys Collab Would Break The Planet

AJ McLean wants to capitalize on a viral mashup of an old Backstreet Boys hit and a new Taylor Swift song … and he’s asking Taylor if she wants to perform with his band in Las Vegas … telling us such a collab would “break the planet.”

We got AJ at LAX on Tuesday and our photog asked him about potentially working with Taylor … who has indicated she likes the “Elizabeth Taylor” and “Everybody” mix.

AJ posted a video on Instagram with the mashup, showing him lip synching … and Taylor commented, “OH HI AJ OH MY GOD.”

BSB shows at The Sphere in Las Vegas have been a huge hit and folks are clamoring for Taylor to join them onstage to perform the remix … and AJ tells us it would be epic.

Taylor’s a BSB fan herself and AJ says she needs to come check out a show first before deciding on a potential collab.
