Beyoncé has fans on the edge of their seats after releasing a six-second video on Wednesday, announcing that there is going to be an announcement on 4.4.13 at 9 a.m. EST.

In the short clip, Beyoncé rocks a sheer black top, shorts, super blond hair, and her glove from the “Single Ladies” video as music plays in the background.

The 31-year-old pop star is shown in an empty studio, and does not say one word. The only other clue to the big reveal tomorrow is at the end of the video, when the phrase #BeyHereNow is displayed.

“4” has always been a significant number for Beyoncé, as she was born on Sept.  4, and her husband, Jay-Z, was born Dec. 4. The couple got married on April 4, 2008. Their daughter, Blue Ivy, was given the name “Ivy” not only because Beyoncé came across a Blue Ivy plant during her pregnancy, but also because “IV” is the Roman numeral for the number “4.” And finally, Beyoncé’s last album was titled, “4.”

So what could Beyoncé’s big announcement be?

She recently released a snippet of her new singles off her upcoming album, “Bow Down/I Been On.” The music video for the songs could premiere tomorrow.  Many fans on Twitter believe she will be releasing yet another song tomorrow.

“#BeyHereNow! Can’t wait to hear @Beyonce’s new single” one fan wrote.

Others think it may be about a TV spot for her Pepsi campaign. She and Pepsi became “global partners” earlier this year, and the New York Times reports that the new partnership is estimated to be a $50 million deal.

What do you think Beyoncé’s announcement is?
