Rainbow, who has been hinting at their comeback mid-February, has just revealed a photo that is sure to tease fans for their return!

Coming on the heels of their first photo teaser, this additional photo is sure to stoke even further the excitement surround this group's comeback.

Fortunately (or unfortunately, depending on your point of view), the girls are wearing shirts this time around, in contrast to their first teaser image, which showed the Rainbow members seductively posing with a huge banner covering their seemingly-bare upper bodies.

As mentioned previously, the 7-member girl group will be releasing an album in one year and 7 months, since 'Sweet Dream' in June of 2011, during the upcoming month.
