" Beyonc\u00C3\u00A9 launched into an impromptu performance of the national anthem at her Super Bowl press conference today (January 31). As the 31-year-old walked on stage for the media event, she asked the assembled journalists to stand, before performing a live rendition of &amp;#039;The Star-Spangled Banner&amp;#039;. Upon finishing the song, she simply asked: &amp;quot;Any questions?&amp;quot; Watch Beyonc\u00C3\u00A9 sing live at the Super Bowl press event below:      The move was a clear attempt to silence her doubters, after it was reported that she lip-synched her performance at President Obama&amp;#039;s inauguration. When asked about the controversy, the &amp;#039;Countdown&amp;#039; singer admitted that she sung over a backing track at the presidential ceremony but defended her decision. &amp;quot;I am a perfectionist,&amp;quot; she explained. &amp;quot;I did not have time to rehearse with the orchestra [at the inauguration]. It was a live television show and a very important moment for me.  &amp;quot;Due to the weather, due to the delay, due to no proper sound check, I did not feel comfortable taking the risk... so I decided to sing along with my pre-recorded track, which is very common in the music industry. And I&amp;#039;m very proud of my performance.&amp;quot; When asked if she planned to sing live at her Super Bowl half-time show, she replied: &amp;quot;I always sing live.&amp;quot; Watch a clip from rehearsals for Beyonc\u00C3\u00A9&amp;#039;s Super Bowl half-time show - to take place on Sunday night (February 2) - below:      "^^<http://www.w3.org/2001/XMLSchema#string>
