Singer IU (whose real name is Lee Ji-eun) sang at her manager’s wedding on Saturday to congratulate the couple.

A YouTube video shows the singer, 23, performing at the wedding. She wore a purple dress and sang her hit dance number “Good Day.”

During the performance, Lee approached the couple and put her microphone in front of her manager. He responded by briefly singing along, much to the amusement of guests.

The video showed guests cheering Lee during her performance. Lee also sang “Proposal,” originally sung by Lee So-ra.
