Sinead O’connor has laughed off comedian Arsenio Hall’s defamation lawsuit.

The Irish singer is being sued for  $5 million after claiming Hall provided Prince with the drugs that allegedly killed him last month.

The funnyman wasn’t laughing as O’Connor reportedly informed authorities investigating the music icon’s death of what she felt she knew, and he filed a libel lawsuit against her earlier this week.

Now the Nothing Compares 2 U singer has responded in a post on her Facebook page.

She stated that she’s more amused than she’s ever dreamed a person could be ,and that she’s looking forward  to how hilarious it will be watching Hall trying to prove her wrong.
