2AM already got into their World Cup supporting spirit when they paired up with Han Hyo Joo to dress as Red Devils for Jambangee. Now, they are in the midst of filming their music video for their World Cup song. Their World Cup song No.1 is going to come with this exciting music video which required 10 extras on set with the boys. Jokwon said, "Even though we're busy and we filmed this throughout the night, because we knew it was for the World Cup, we weren't tired at all. This was a music video we filmed happily so we hope everyone else enjoys it." The song will be released on the 20th and the music video will follow soon after.
