Beyoncé continues to tease fans about her upcoming Super Bowl halftime show performance this Sunday.

The R&B diva released a video of her first day of rehearsals for the big show on her Tumblr page Wednesday evening.

The 42 second clip features Beyoncé with a plethora of back up dancers practicing for the performance. At one point, Beyonce can even be seen on her computer, supposedly uploading rehearsal footage onto her Tumblr.

The video, set to her hit single “Countdown,” does not give very much detail, however, dancers are seen doing some of the iconic moves from the music video for another hit single of hers, “Single Ladies.”

Beyoncé is set to hold a Super Bowl halftime show news conference Thursday where several sources expect that she may give details about her set-list and other tidbits about the show.

There is still speculation about whether her fellow Destiny’s Child members, Kelly Rowland and Michelle Williams will join her during the performance.

While Williams has public stated that she is not available for the show, the Shakespeare Theatre Company that is hosting a Washington D.C. performance of her musical “Fela!” notes that the singer will not be will not be appearing in shows from Jan. 31 to Feb. 3.

Mystery continues to shroud Beyoncé’s Super Bowl performance, which will likely translate into a high number of viewers for this year’s half time show.
