On her personal blog, O'Connor wrote:

    "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. We will post a photo or two here on the site as soon as possible afterward. Very happy girl. : ) "


In September, the "Nothing Compares 2 U" singer wrote she was "desperate for sex" on her blog. Hmmm ... guess her wishes have been granted.

This will be O'Connor's fourth marriage.
