In addition to a new album and her Mrs. Carter Show world tour, Beyonce has another project in her busy pipeline: A new track for the 'Epic' soundtrack. Queen Bey, who voices Queen Tara in the animated flick, contributed the original song for the film -- and had some stellar help.

Global Grind reports that Bey worked with Sia, who penned Rihanna's 'Diamonds,' as well as producer Hit-Boy, who worked on 'Bow Down' and 'N----s in Paris' for her hubby Jay-Z and pal Kanye West.

In a new interview with 'Good Morning America,' Beyonce revealed that a big perk of the 'Epic' role is earning "cool points" with baby girl Blue Ivy. Bey accepted the role when she was pregnant with the adorable baby girl, and it was a deliberate decision. It was also the first project she worked on following Blue's birth.

"It has so much depth. You know, it’s so emotional," the 'Countdown' singer gushed. "And I literally, I was crying when I — when I did the voice-over. And it was the first thing I did after giving birth. And there's a scene where I pick the pod. And literally there were … tears falling."
