The members of SISTAR unintentionally stole(?) the spotlight at a former manager's wedding, held this past weekend on May 14.

On this day, the complete lineup of Starship Entertainment artists (except CRAVITY, due to their concert schedule) attended the wedding of a manager, including K.Will, SISTAR, Yoo Seung Woo, MONSTA X, Wonho, former Boyfriend member Minwoo, Jung Se Woon, Cosmic Girls, and IVE. Jung Se Woon fulfilled the role of MC, while K.Will was scheduled to sing the congratulatory song.

However, it was revealed on the spot that K.Will could not sing due to problems with his throat. The singer then requested that the members of SISTAR come up to sing a congratulatory song on the fly, and the four members including Hyolyn, Soyu, Bora, and Dasom happily obliged. 

The four ladies performed their hit song "Loving U" perfectly even though the performance was totally unplanned, receiving a flurry of applause from attendees. The members furthermore garnered attention for their high energy throughout performance as well as after the ceremony, bubbling with excitement at the wedding of a manager who worked with the group during SISTAR's busiest days. 

In particular, the flashy poses of SISTAR's unnie-line members during a group photo with all Starship Entertainment artists brought much laughter. 

Check out some photos from the wedding, including some shared by Hyolyn on her Instagram, below!
