US comedian Arsenio Hall is suing Sinead O’Connor over a Facebook post in which the singer accused him of supplying Prince with drugs.
The libel lawsuit filed in Los Angeles Superior Court calls O’Connor’s accusations fabricated lies.
The lawsuit says O’Connor, who scored a hit in 1990 with her version of Prince’s Nothing Compares 2 U, barely knew the superstar and despised him.
O’Connor wrote a Facebook post on Monday that said investigators looking into the supply of drugs used by Prince should question Hall. She also accused him of drugging her.
The lawsuit seeks more than 5 million dollars (£3.4 million) in damages but any award would be decided by a jury.
