IU’s hot cover of “Trouble Maker” during her first concert is currently making abuzz amongst netizens.

A number of online community boards were posted with a video of IU’s “Trouble Maker” performance at her first solo concert “Real Fantasy.”

In the clip, IU came up with a series of dances. The singer first dressed fittingly into a more masculine attire and danced to Black Eyed Pea’s “Boom Boom Boom”, Rain’s “Rainism” and Michael Jackson’s “Dangerous.”

IU then wrapped up her dance segment “Troublemaker” as HyunA in the choreography. She confidently showed off her hidden talent in dancing and melted the fans with her sexy charms.
