NEW ORLEANS — Beyonce is expected to face the media Thursday as she previews her halftime performance at the Super Bowl. But the focus will likely be on her performance at that other big event earlier this month.

The superstar hasn't spoken publicly since it was alleged that she lip-synched her rendition of "The Star-Spangled Banner" at President Barack Obama's inauguration last week. Her critically praised performance came under scrutiny less than a day later when a representative from the U.S. Marine Band said she wasn't singing live and the band's accompanying performance was taped. Shortly after, the group backed off its initial statement and said no one could tell if she was singing live or not.

It's expected that the halftime performance will be a main focus of her afternoon press conference, even though she'd likely rather concentrate on questions about her set list for Sunday and her upcoming HBO documentary, "Life Is but a Dream." The documentary is being shown for the media just before Beyonce speaks and takes questions, as expected.

There has been plenty of speculation about Beyonce's Super Bowl performance, including reports there would be a Destiny's Child reunion with Michelle Williams and Kelly Rowland (Williams has shot down such speculation). Some are also curious about whether her husband, Jay-Z, will join her onstage, as they often do for each other's shows.

Beyonce has teased photos and video of herself preparing for the show, which will perhaps be the biggest audience of her career. Last year, Madonna's halftime performance was the most-watched Super Bowl halftime performance ever, with an average of 114 million viewers. It garnered more viewers than the game itself, which was the most-watched U.S. TV event in history.
