A jury at the High Court in Dublin deliberated for a day before reaching a verdict that McGregor had assaulted Ms Hand.
She also took the case against another man, James Lawrence, 35, of Rafters Road, Drimno in Dublin.
She claimed he assaulted her by having sex with her without her consent at the Beacon Hotel.
The jury found that he did not assault her.
Ms Hand told reporters she was “overwhelmed and touched” by the support she had received.
She added: “I want to show (my daughter) Freya and all other young girls and boys that you can stand up for yourself if something happens to you, no matter who the person is, and that justice will be served.”
