Beyonce Knowles said she mimed during her performance at Barack Obama's Inauguration Day because she is "a perfectionist."
At a NFL Super Bowl event in New Orleans the singer explained that she hadn't had a chance to rehearse with the orchestra and wanted to make the president proud.
Beyonce started the press conference with a live performance of her national anthem before asking the assembled journalists: "Any questions?"
Beyonce appears to have broken her silence over the 'lip-synching' controversy by posting a photograph of herself online wearing a jumper with the slogan: 'Can I Live?'.
The singer is thought to have 'lip-synched' the national anthem during a performance at President Obama's inauguration due to a lack of rehearsal time with the band. But up until now, she had remained tight-lipped about the incident.
The inauguration performance has prompted speculation about Beyonce's planned appearance at the Superbowl's half time show on February 3.
The top is also thought to be in reference to her husband Jay-Z's song titled 'Can I Live'.
Beyonce has announced she is reuniting with her Destiny's Child band mates for a new album - their first in eight years.
The songstress wrote on her official website, "I am so proud to announce the first original Destiny's Child music in eight years!"
The album, titled Love Songs, is due for release on 29 January.
