Two of the biggest pop divas in music today are joining forces. Former VMA rivals Beyonce and Lady Gaga are going half on an upcoming music video that will accompany Bey’s new single, “Video Phone,” industry tattles snitch.

“On Oct. 7, Lady Gaga and Beyoncé were working on the video together at a studio in NYC,” a spywitness reveals in the October 26 issue of Life & Style. “Everything on the set was being kept very hush-hush, and security was extremely tight.”

The girls — both known for their elaborate costumes and action-packed stage shows — and the video promises plenty of that, sources say: “In the video, Beyoncé wears a feathered dress. And of course Lady Gaga wears something wild. The fashion is sick and insane.”
