Choreographer Jonte Moaning, best known for his work with Beyonce's "Single Ladies", has been revealed to be working with T-ara for their comeback album!

Moaning worked with miss A for their "Touch" choreography, and this time he's teamed up with T-ara for their "Day by Day" comeback next month.

Representatives of Core Contents Media stated, "T-ara's dance team visited New York for six days, and were taught the 'Day by Day' choreography by Moaning himself."

To raise anticipation for the comeback, a video featuring Moaning will be released giving fans a glimpse of the choreography and T-ara's new song on May 24.

However, prior to its official release, a leaked version of the video has been circulating online. A Core Contents Media representative stated, "T-ara's new song, which was originally scheduled for release in July, and Gang Kiz's follow-up song and choreography were leaked on YouTube."

They continued, "The choreography is special in that our dance team went to New York for six days to learn it under 'Single Ladies' choreographer Jonte Moaning. Only our representatives from Japan and the U.S. were present to record the choreography so we're trying to figure out how the leak happened. We'll be taking this internationally."

Core Contents Media is currently investigating the case, and will be filing lawsuits against those involved in the leak.
