A little over a month ago, Half-Korean / American R&B singer Amerie released a new version of her track Heard 'Em All, and featured girl group 4minute along with BEAST's Junhyung. We recently reported that Amerie would perform Heard 'Em All along with 4minute on March 26th's KBS Music Bank. But before that happens, they recently performed together at a posh W Hotel for the KIA Motors Auto Show. SSTV was on hand to record the whole performance and the girls looked fierce. On the 25th, she's scheduled to hold a fan meeting at the Mnet studio in Seoul and of course she'll wrap it all up on the 26th with one big performance on KBS Music Bank. Check out the KIA Motors performance below and thanks to heechulisnotgay for the tip.
