Arsenio Hall was quick to deliver a $5 million defamation lawsuit against Sinead O’Connor after she accused the ex-talk show host of supplying drugs to Prince. Shockingly, the pop singer finds Hall’s lawsuit amusing.

In a snarky Facebook post, which she titled, “Regarding Arse-inio Hall’s Laughable Threats,” O’Connor doesn’t seem too worried about Hall’s legal threats against her. She writes:

I'm more amused than I've ever dreamed a person could be and look forward very much to how hilarious it will be watching him trying to prove me wrong.
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---. That is if he isn't too busy sucking someone else's d---. :)"

O'Connor's snarky post follows on the heels of O'Connor writing a lengthy Facebook message, which has since been deleted, where she accused Hall of supplying Prince with drugs and allegedly "spiking her drink" at a party at Eddie Murphy's home years ago.

The 60-year-old television veteran has denied all accusations in his $5 million lawsuit against the "Nothing Compares 2 U" singer. In his suit, Hall describes O’Connor as “desperate” and an “attention-seeker.” He says the singer’s claims has “maliciously” hurted his reputation.
