After announcing their official comeback yesterday, the members of 4minute followed up by releasing their photo teasers today! Living up to their album's "STEAL 20" concept, the girls showed their determination to "unlock themselves as they step through the doorway into their 20s, an age capable of keeping secrets." [gallery] Representatives of Cube Entertainment described, "HyunA is seen dressing up, which is an expression of preparing herself to begin life in her 20s. Gayoon completed her cut with a sense of emotional maturity. Jiyoon, who's always been known for her boyish style, made a sexy transformation with a black tank top, while leader Jihyun donned a dress accentuating her beautiful silhouette. Sohyun expressed the romantic fantasies and dreams of turning 20 with her curious gaze." 4minute will be releasing their teaser video on the 24th, followed by the album's official release on the 29th.
