Brown Eyed Girls' Ga In has left us all curious with a new photo of her recording in the studio.

Nega Network's CEO updated fans on Twitter writing, "Miss Son recording...Isn't she pretty? Whose song? What kind of song could it possibly be?", leaving fans tweeting him their various guesses.

Since it's been said that Brown Eyed Girls are planning to make a comeback this July or August, according to music industry insiders, many presume that this could possibly be for that! However, some also predict that this could be a sign that the singer may be working on another solo release, or perhaps even featuring in the album of the soon-to-debut male idol group from her agency, currently nicknamed, 'Brown Eyed Boys'.

What are your guesses?
