Seohyun, Bada, and Shoo Practice for “Infinity Challenge”

S.E.S’ Shoo, Bada, and Girls’ Generation’s Seohyun have come together to practice for their performance on MBC’s “Infinity Challenge” special “Saturday Saturday is Singer” episode.

“There is nothing in life but to practice! One, two, three, let’s get this straight~ Oops! Looks like I forgot my steps,” Bada posted on her Twitter account. “This is our last rehearsal, and our knees are bruised. Ouchie ouchie.”

The trio’s diligent efforts have kept audiences in high anticipation of the upcoming special episode.

Seohyun stepped in for S.E.S’ Eugene, who won’t be able to perform with her band because of her pregnancy.

The episode will be filmed in Ilsan on December 18.
