NEW ORLEANS (AP) -- Beyonce says she did lip sync when she performed the national anthem on Inauguration Day.
The singer held a press conference Thursday in New Orleans days ahead of her half-time performance at the Super Bowl.
She said she's a "perfectionist" and wanted her performance for President Barack Obama to be a memorable one. She called the day "emotional."
Beyonce opened the press conference with live rendition of the national anthem.
