Singer Sinead O'Connor has announced that she will be walking down the aisle on Thursday for her 45th birthday.

With enormous joy myself and my beloved boyfriend Barry Herridge will be getting married tomorrow, December 8th 2011 at 'an un-disclosed location' in my absolute dream wedding ceremony, O'connor wrote on her Web site. We will post a photo or two here on the site as soon as possible afterward.

The Nothing Compares 2 U singer also said that she is a very happy girl.

According to People.com, this will be the Irish singer's fourth marriage. She divorced longtime friend and collaborator Steve Cooney in April after eight months, People.com reported, noting that O'Connor wed music producer John Reynolds in 1989 and journalist Nicholas Sommerlad in 2001.

O'Connor has four children from her previous relationships.
