I'm glad they finally addressed it, but I have a feeling they're just saying its a 'hiatus' because they don't want to say she's leaving yet...I do think she will release a statement at some point deciding to leave. She just seems so burnt out to me and like she enjoys singing/dancing, but not the whole fame side of things (which is understandable). I feel like its even harder when you've spent your formative years in the public eye.
I still think the rest of the girls will pretty much take a hiatus too, as they don't have much else to promote and I think the tour isn't supposed to happen until May.
