Beyonce is working extra hard to have a spectacular halftime performance At Super Bowl, after the lip-syncing controversy from President Obama's inauguration. According to AP she will finally speak out about publicly about that on Thursday.

According to New York Daily New, "Beyonce was accused of not singing the National Anthem live when a spokesperson for the Marine Corps Band claimed she used a pre-recorded track instead of singing live. Then hours later it was retracted with another statement from the band saying, "No one in the Marine Band is in a position to assess whether it was live or pre-recorded."

"The singer, who is usually dressed to the nines, was seen Tuesday with mom Tina Knowles prepping for the big show make-up free and in workout clothes and hat and to prove how serious she is about the show. She even posted her own pesonal pics of rehearsals that day to her Tumblr page."

"Beyonce may have stepped out with a stripped face this week but she surely glammed it up for her promo shots for Sunday's big game. She looks super sexy in her revealing referee gear and red-hot lips."

She cannot miss this show, nor not having it at the top, because the SuperBowl is one of the most watched sport event in the world, and an opportunity for any singer to attract new fans, as The Who frontman Roger Daltrey said : "the Super Bowl is an opportunity for increased exposure, even for a band that's already sold 100 million records. You can be touring like we have for 50 years, and there's billions of people who have still never heard of you. That's the nature of the media these days."
