Singer Baek Ah Yeon, who rose to fame through the first season of SBS ‘K-Pop Star’, will be making her music comeback after nine months of hiatus since debuting with first album ‘I’m Baek’ last year.

Baek Ah Yeon will release her second mini album titled ‘A Good Girl’ later this month. While fans speculated for miss A’s comeback with their previous tweets, it turned out that the girls are just lending a hand to promote Ah Yeon’s return.
