Sinead O'Connor and Barry Herridge

Sinead O'Connor probably had one of the most bizarre break-ups of 2012. The Irish singer and Barry Herridge wed in early December, 2011 -- only to split two weeks later. They reconciled, but then parted ways again just two weeks into 2012. O'Connor wrote a series of blog posts on the subject, sometimes blaming the media for her marriage troubles.
