Rihanna is being sued for defamation by her Dublin based former head of security.
The order to serve notice on the pop star was made in the High Court yesterday.
Geoffrey Keating with an address at Woodbank Drive, Valley Park, Finglas was Rihanna's former head of security when she was on tour from October 2012 to July 2013.
Now he is suing the singer for allegedly making defamatory comments in a series of statements in an e-mail to his wife last July and in a phone call to his sister.
Mr Keating says the allegations, which were not outlined in court, are untrue and that they have gravely injured his reputation and his business.
He is seeking damages and also wants the singer to publish a correction.
