Bada SHARED PHOTOS from a practice session with Seohyun and Shoo!
 

The Girls' Generation member was recruited to take the place of Eugene for S.E.S' upcoming appearance on 'INFINITY Challenge's year-end special. Bada posted the photos above and the message, "Practice is the only way! 1.2.3 Right on the beat~. Forgot the choreography I see. Our last practice session. Seohyun became Eugene, her knee was bruised, and Shoo's knees got bloody and bruised."

It looks like the trio are working hard for the upcoming special! As previously mentioned, the 'ToToGa' (short for 'to-yo-il to-yo-il-eun gasoo-dah' which means 'Saturday, Saturday is a Singer') special, planned by Park Myung Soo and Jung Jun Ha, will bring popular '90s artists for a year-end performance. It will be filmed at MBC Dream Center in Ilsan on December 18.
