Last week, Beyonce debuted her fifth commercial for Pepsi, featuring a new song called “Grown Woman” — which is set to be released soon (maybe? we’re keeping hope alive here!) — and this week, a new 12-second preview video featuring more of the track was released that appeared to show some new, never-before-seen behind the scenes video footage.

But as it turns out, the footage comes from the behind the scenes video we posted over the weekend from the taping of the “Mirrors” Pepsi commercial. Apparently, an audio-savvy fan took the background music from the aforementioned clip, raised the volume and combined it with the video footage, passing it off as a “preview” for the single.

“Grown Woman” is a song off Beyonce’s still-untitled fifth studio album (though rumors suggest it will be called “Mrs. Carter”), but her reps have made it clear that the Timbaland-produced track is NOT the first official single from the album, which — other than “Bow Down / I Been On” — we have yet to hear virtually ANYTHING from … despite the fact that her world tour kicks off next Monday (Apr 15) in Serbia.
