Beyonce's 'Run The World (Girls)' To Hit Radio, iTunes Thursday

Singer has also posted a 17-second video teaser on her website.

A demo version of Beyoncé's new single "Run the World (Girls)" may have made the rounds online earlier this week, and now the singer will unveil the official version sooner than expected.

According to a press release, the club-ready tune, which samples Major Lazer's "Pon de Floor," will hit radio airwaves and iTunes worldwide on Thursday.

Produced by Switch, Beyoncé and Shea Taylor, "Run the World (Girls)" is the lead single from the pop star's yet-untitled fourth studio album. Like her previous smash "Single Ladies (Put a Ring on It)," the singer wrote the girl-power anthem with the help of R&B mastermind The-Dream.

If that weren't enough to appease fans' appetites, the entertainer has also released a 17-second video teaser called the "B Revolution" on her website. The teaser, which appears to be a taste of the song's forthcoming video, begins with a shot of a sunset, a rusty dark car with the word "Revolution" painted on it and a shredded newspaper. B soon appears in an all-white ensemble on top of a horse, which lifts its legs high in the air. The clip appropriately ends with the singer's new "B" logo and the iTunes release message.

While not much is known about the video plot for "Run the World (Girls)," MTV News was lucky enough to speak with the clip's director, Francis Lawrence, on Sunday. "The video's for the songs 'Girls'; it's off her new album," he confirmed. "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."

Despite Lawrence's attempt to stay mum on details, the director revealed that the clip will be a standout among the singer's videography. "It'll be big. It'll probably be one of the bigger Beyoncé music videos ever done," he said. "And I can say that I think the song is unbelievable."
