It's been belatedly revealed that f(x)'s Sulli was hospitalized for abdominal pain.

A rep from SM Entertainment stated that on March 27, she was sent to the hospital to receive emergency treatment after complaining of abdominal pain. The rep said, "It's true that she went to the emergency room. They suspected it was her appendix, but after examination, that was ruled out."

Sulli recently wrapped up filming for the film 'Pirates' and is in the midst of filming for the movie 'Fashion King', and it seems she's had a hard schedule. The rep continued, "It was stress-related pain. After returning from the emergency room, she is resting."

Hopefully, Sulli will feel better soon.
