Apparently, last week the singer was filming a video for her newest song in LA. However, a source claimed to Reality Tea that there was “presidential-level secrecy” around it. That meant the crew had no idea what it was about, because they couldn’t hear it. This report also claimed that everyone working on the project had to sign NDAs, too.

The pop icon was spotted filming a “top secret” music video in Los Angeles on Thursday. It was reportedly so covert that crew members weren’t even allowed to hear the actual track — just the beat. That level of lockdown is rare, even for Swift, and it’s got fans losing it.
