BEYONCE has been holed up in a studio in New York working on her next album with Kanye West and hubby Jay-Z’s producer Hit-Boy. And the singer is taking no chances with her new material being leaked. A source said: “She’s spent thousands hiring out the whole studios. She’s got security on the doors to ensure no one hears a whisper. “She’s being strict with proceedings too, putting in 14-hour days declaring nobody leaves until it’s perfect.”
