SISTAR’s Bora has suffered a burn injury during Friday’s rehearsal for KBS “Music Bank,” local media reported. She was rehearsing for the performance of SISTAR’s latest single, “So Cool,” at the time of the accident.

During the rehearsal, Eun Ji Won and the rest of the KBS “One Night Two Days” team came to visit the show. Bora went to greet the special guests, but she tripped and fell on one of the stage lightings, according to reports.

“Bora burned her thighs after falling on one of the stage lights. She received emergency treatment at the hospital and she’s back preparing for her comeback performance, but we’re concerned that it might leave a scar,” SISTAR’s representative told Star News.

SISTAR returned with their first full album and title track, “So Cool,” on August 9th. They made their first comeback performance on August 11th on Mnet’s “M! Countdown!” and are scheduled to perform at KBS “Music Bank” tonight.
