The five ladies of f(x) have returned to Music Core with a nice surprise for their fans. Today, the girls performed their much awaited follow-up single Mr. Boogie.

The song has been a favorite amongst fans since it’s release, so many have been anticipating today’s performance for quite some time. Amber was still missing though as f(x) performed the catchy single in today’s pre-recorded episode of Music Core.
