(CNN) U.S. comedian Arsenio Hall is suing singer Sinead O'Connor for defamation.

This is after she posted a note on Facebook accusing Hall of supplying Prince with drugs "over the decades" and of spiking her with drugs.

The suit, filed in Los Angeles on Thursday, is seeking damages of "not less than" $5 million.

"Desperate, attention seeker Sinead O'Connor has maliciously published outlandish defamatory lies about comedian Arsenio Hall, falsely accusing him of supplying illegal 'hard drugs' 'over the decades' to the recently deceased music artist, Prince, and of spiking her with drugs once years ago," the lawsuit says.
