After first accusing Arsenio Hall of supplying Prince with drugs prior to his death, Sinead O'Connor is now unapologetically lashing out at the comedian now that he's taken legal action against her. Three words that summed up her sentiments: "suck my d**k."

In a pretty graphic Facebook post, the "Nothing Compares 2 U" singer held no punches in expressing just how she felt about Arsenio's decision to sue her.

"I'm more amnused than I've ever dreamed a person could be and look forward very much to how hilarious it will be watching him try to prove me wrong," she wrote. "I'm also very happy to notice that the DEA have taken me seriously enough to be thoroughly questioning all of Prince's friends and aides from the last thirty years as to his KNOWN history of hard drug use and where he obtained his drugs. I do not like drugs killing musicians. And I do not like Arsenio Hall. He can suck my d**k. That is if he isn't too busy sucking someone else's d**k. : )" 

Their feud started back when O'Connor accused the Coming to America actor of delivering drugs to the fallen legend. She explained it all in an earlier Facebook post, saying, "Anyone imagining Prince was not a long time hard drug user is living in cloud cuckoo land. Arsenio I've reported you to the Carver County Sherrif's [sic] office. Expect their call."
