The back-and-forth between Miley Cyrus and Sinead O'Connor is back again.
It all began when Cyrus gave a nod to O'Connor in a recent interview with Rolling Stone, claiming her "Wrecking Ball" video was a "modern version" of O'Connor's iconic "Nothing Compares 2 U" clip. But O'Connor is no fan of Cyrus' stripped down video or the state of the music business that fostered it — which she plainly stated in a lengthy open letter to the former "Hannah Montana" star. 
That sparked a reaction from Cyrus, who tweeted a screen shot of past posts O'Connor made when she was seeking psychiatric help and put it under the heading "before Amanda Bynes…. There was…."
Now? The situation seems far from over.
Anyone catch what's going on between these two singers? What are your thoughts? Was Sinead trying to help? Does Miley even need the help?
