The inevitable pairing of pop mistresses, Lady Gaga and Beyonce Knowles, has finally taken place and under the shroud of secrecy. Life & Style reports that earlier this month, the two ladies met up for a highly covert meeting at a studio in NYC.

Their mission? To film the music video for Beyonce’s upcoming single, “Video Phone.” An inside source dished to the mag, “Beyonce wears a feathered dress. And of course Lady Gaga wears something wild. The fashion is sick and insane.”

I’m not a math whiz, but I do know know this. Sasha Fierce + Lady GaGa should definitely = fabulousness.
