We reported quite a while ago that Amerie was going to feature 4minute and BEAST's Junhyung in her newest album, In Love & War. Shortly after, the song they were featured on got released. Now, it seems like Amerie and the girls are getting ready for a live performance of this song. The song, Heard 'Em All, is a hot track that requires some dance moves to go along with it. Amerie said upon meeting the girls,

"They're so pretty and lovable. I've already heard Hot Issue."

Amerie arrived right after a 12 hour flight but she didn't fail to impress. She added her own choreography, altered it for 4minute and really worked together. She made sure the practice wasn't going on too late and tiring for the girls. 4minute's dance instructor said,

"She is a true professional."

Amerie and 4minute will perform together in Korea at the W Hotel for the KIA Motors car launch event. Amerie will also visit Bae Chul Soo's radio show, hold a fanmeeting at the Mnet studios and perform with 4minute again on Music Bank while she is in Korea.
