Beyonce Knowles is ready to play some football!

The singer, who will perform during the halftime show for Super Bowl XLVII, sports a sexy referee's uniform, eye black and a pair of Christian Louboutin boots in a new promo for game day.

The performance will be her first since lip-synching the National Anthem for President Barack Obama's inauguration last week.

From the looks of some of the rehearsal photos, Bey is definitely going to be dancing up a storm ... and we're guessing she's going to quiet naysayers by singing live this time.

Check out the gallery above to see more photos of a sweaty Knowles rehearsing for the big day.

It's been reported that the rest of Destiny's Child will join Beyonce on stage for her performance -- but Michelle Williams shot down the rumors in a recent interview.

"I'm going to be in the musical Fela!," she told WRUG Media. "I hate to disappoint the people and tell them that it's not true."  

Of course, she could be lying to keep up the element of surprise.

Do you hope they pop up for the performance? Sound off below.
