A $5 million lawsuit was filed against singer-songwriter Sinead O'Connor in relation to the death of musician, Prince. The lawsuit comes after the Irish singer alleged Arsenio Hall of providing drugs to the late singer on a social media post.

Comedian Arsenio Hall filed a defamation lawsuit against Sinead O'Connor last Thursday following the singer's Facebook post wherein she alleged that Prince received drugs from Hall, ABC News reported. O'Connor wrote on her post that she was responding over the former TV host's "laughable threats".

"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," O'Connor posted.

She also repeatedly wrote she hates Arsenio Hall. The 49-year old singer also followed her Facebook post with a Youtube video, containing her song, "Nothing Compares 2 U" in which she captioned as a tribute for Prince's death.

O'Connor mentioned Prince was "not a long time hard drug user," and that she had reported the 1989 to 1994 talk show host to Minneapolis Carver County police department, Stuff.co.nz reported. She also posted a video, showing her guest appearance on Hall's talk show, "The Arsenio Hall Show" prior to her controversial boycott on Grammy Awards back in the year 1991.

Hall filed the legal complaint on the Los Angeles Superior Court, wherein he called the singer, a "desperate, attention-seeker, now known perhaps as much for her bizarre, unhinged internet rants as for her music." O'Connor also pointed out that she don't like drugs and killing musicians, also noting that Prince got his drugs from the US talkshow host "over the decades," Billboard reported.

The complaint seeks $US 5 million in compensatory damages as well as a punitive amount of damages as a deterrence to others. Prince died last month at the age of 57 at his Paisley Park compound in Minnesota.
