f(x)'s Amber has finally re-emerged after a six-month absence from the group's activities. The singer's schedule came to an abrupt stop last June due to an ankle injury. On December 2nd, Amber was seen attending SHINee's concert.  SM Entertainment officials stated, "Amber has returned to Korea for the year-end.  It is true that she visited SHINee's concert.  Her condition has improved a lot after resting in the U.S." They continued, "Amber will continue to rest while preparing for f(x)'s next album.  We are currently deciding on the date for their comeback." Her return seems to have put an end to the disbandment rumors surrounding the group since her leave. Source + Photos: Sports Chosun via Daum
