In lieu of her upcoming world tour, Beyonce Knowles unleashed a brand new song today on her official Tumblr page. Check out the song, title "Bow Down/I Been On," below!

There's no word yet on whether or not the single will be featured on an upcoming album or not - Sasha Fierce herself hasn't made the announcement as to whether or not a new album is even coming. But with her explosive Super Bowl performance and reemergence into the spotlight, there's surely a good chance.

Following her historic performance tonight at the Pepsi SuperBowl XLVII Halftime Show, in New Orleans, Louisiana, Beyonce officially returns to a full-time touring schedule, her first since the I AMWORLD TOUR in 2009, with a new, bolder state-of-the-art production.
