Girls' Generation has released a new teamwork photo ahead of the release of their new song on December 21st!

Unlike the first photo, which appeared to be a logo for their upcoming comeback, this photo shows the girls' hands gathered all together in unison, showing off their camaraderie and teamwork.

One insider had revealed,�"There is a rumor that the song that will be pre-released is one that has been worked hard on, as much as a title track, so I'm looking forward to it." There are also rumors that�this pre-release coming up is actually a remake of a famous song and that the girls have worked on it years ago, but are now using this chance to reveal the track.

Are you ready for Girls' Generation's new song?
