f(x)'s Amber is beginning preparations for the group's comeback! A broadcast representative alerted fans of her comeback through his Twitter by writing, "You guys asked me about f(x) Amber's comeback last time, right?  She has returned, and will be joining f(x)'s album, scheduled for release in February. You'll be able to see her official activities next month!" Amber has been away in the U.S. for six months due to an ankle injury, leading fans to speculate whether she was leaving the group.  Fortunately, she made an appearance at SHINee's first concert, which stemmed the rumors once and for all. Her condition has been reported to be vastly improved, enough for her to join the group for their next album promotions. Source + Photos: Newsen via Daum, Daily Sports via Naver
