Louis Walsh's lawyer said after today's verdict that the story about his client "should never have been published".
Paul Tweed confirmed that Walsh would be paid damages of more than £400,000 along with his legal costs.
He added that the case highlights the "serious damage that can be inflicted on an individual ... by the publication of totally unfounded allegations which, in the age of the internet, can circumnavigate the globe in a matter of seconds."
