Sinad O'Connor is getting married tomorrow.

The Irish singer has confirmed she is tying the knot with her partner Barry Herridge.

The nuptials will take place on the star's 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. We will post a photo or two here on the site as soon as possible afterward.

Very happy girl. :) ," she wrote on her blog.

This will be Sinad's fourth wedding, with her divorce from her third husband Steve Cooney finalised in April of this year.

The star has also been married to John Reynolds and Nicholas Sommerlad and has four children.

There are reports her big day will take place in Las Vegas, although they are yet to be confirmed.

Sinad has caused controversy recently after writing about how keen she was to find a man on her blog. She even put a call out to possible candidates, admitting she was "desperate for sexI am in the peak of my sexual prime and way too lovely to be living like a nun, and it's very depressing".
