SHINee's new hairstyles for Japan debut revealed?

A mastering engineer from Sonic Korea recently tweeted that he was currently "mastering SHINee's Japan debut single!"

It is speculated that SHINee will be shooting their PV next week. According to rumor, their music video concept will include Taemin as a "dancing machine," Key as a fashion designer, Onew as a painter, Jonghyun as a singer, and Minho as an athlete. Another rumor says that SNSD's Yoona will featured in the video.

A fan posted photos of both Taemin and Key with new hairstyles on a SHINee fan community, DC SHINee Gallery. The images show Taemin with red hair and Key with blonde hair. Minho and Onew, on the other hand, showed off their similar curly new hairstyles on Music Core. Jonghyun's new look has yet to be revealed.

Taking in consideration both the tweet and new hairstyles, SHINee's debut in Japan is predicted to take place sometime in May.
