Beehive, brace yourselves: Rumor has it Beyoncé lip-synched the National Anthem.

After performing a rousing rendition of “The Star-Spangled Banner” during President Obama’s public swearing-in, the pop star earned praise all the way from Washington’s cheering crowd to the social media sphere.

But now Beyoncé may face backlash as it’s been revealed that she fell back on a “pre-recording” rather than risking it live during the inaugural ceremony on the steps of the U.S. Capitol on Monday.

“We all know Beyonce can sing,” Master Sgt. of the U.S. Marine Corps Band Kristin Dubois told ABC News. “We all know the Marine Corps Band can play. We do not know why she decided to go with the pre-recorded music at the last minute.”

The evening before Inauguration Day, Beyoncé laid down her her rendition of the tune — sharing behind-the-scenes snaps of the recording studio session— which Dubois explained is common procedure in case anything goes awry during the oath of office ceremony.

“I’ve been with the band 14 years. It’s not unusual,” said Dubois, adding that “You can’t have an inaugural without the National Anthem.”

Then just before stepping front-and-center on the stage Monday, Beyoncé decided to ditch her live vocals, opting to rely on the pre-recorded renditions. Even though the director continued to conduct as the Grammy-winning singer lip-synced, the Marine Corps. band was instructed not to play for the performance, raising eyebrows among inauguration-goers and at-home viewers.

But Beyoncé isn’t the first to forgo an on-the-spot performance for an Obama inauguration. Back in 2009, the cellist Yo-Yo Ma and the violinist Itzhak Perlman, two of the most beloved figures in classical music, performed to a playback version of “Air and Simple Gifts,” understandable given that the freezing temperatures and gusting winds on that day.

Now the world is left wondering: If she was for-real faking it, why did Beyoncé ever-so-dramatically pull her ear piece out during the performance? That may be a question only Queen B can answer.
