Sinead O'Connor isn't playing nice with Miley Cyrus anymore -- in fact, she's warning the pop tart to stop dissing her or risk a lawsuit.
Sinead is ticked that Miley responded to her unsolicited advice about how to behave by re-tweeting some things that she'd sent out during a dark period in her life last year. In response to being compared toAmanda Bynes, Sinead wrote a note saying, “Ms. Cyrus has today posted tweets of mine which are two years old and which were sent when I was ill and seeking medical help. She has done this in an attempt to deliberately cause me harm and hurt. Ms. Cyrus’s lawyers will be contacted by mine regarding this matter."
Miley then spent time tweeting that she didn't have time to deal with Sinead and mocking the older singer's current career, which led Sinead to defend Amanda and then jab Miley by saying, “Soon it will be you who will be the media ‘crazy’...and you will not enjoy it. When you end up in the psych ward or rehab, I’ll be happy to visit you...and would not lower myself to mock you."
