Beyoncé's 'Girls' video is "big", says director

Francis Lawrence has revealed that Beyoncé's recently-filmed music video for new single 'Girls (Who Rule The World)' is one of her her biggest to date.

The Hollywood director, who has previously worked with Lady GaGa on her 'Bad Romance' video, has promised that the video will live up to fans' expectations.

"I just shot a Beyoncé video at the beginning of this last week - Monday, Tuesday, Wednesday - which was fun, and I hadn't done a video since 2009," he told MTV.

"The video's for the song 'Girls' - it's off her new album. She would probably have me shot if I said anything... Some stuff spilled out, but she wasn't happy about it, so I've been sworn to secrecy."

Paparazzi shots of the filming of the video in the Mojave desert in California appeared online last week, showing the diva in an array of outfits, standing on overturned cars in a revolution-inspired scene.

"It'll be big - it'll probably be one of the bigger Beyoncé music videos ever done. And, I can say that I think the song is unbelievable," he added.

No release date for this single has yet been confirmed, but a version of the track leaked online earlier today.

Beyoncé's new album is expected to be released this June.
