If rumors are to be believed, word on the street is that f(x)'s Sulli is leaving the group to focus on her acting career.

Of course no word has come from SM Entertainment yet, but according to what Herald Review Star has discovered from insiders in the scene, Sulli will be leaving the group but will be remaining under contract with SM Entertainment.

This may mean that the group may reorganize as a 4 member girl group and the expected comeback is thought to be around September.

Stay tuned for any updates to come regarding this rumor.
