SPICA and their agency B2M Entertainment recently hinted through Twitter that the girls would be making a comeback soon, but that's not the only good news!  They revealed that Lee Hyori would be trying her hand as a producer, lyric writer, and composer for SPICA's new song.

The Tweet said, "Lee Hyori's formal debut as a producer.  In charge of writing and composing SPICA's new song."

While Lee Hyori had previously written the lyrics for SPICA's "Tonight," the song had been an arrangement of a preexisting foreign song.  However, this time, she will take part in the whole process to create a completely new song for the girls!
