DUBLIN, IRELAND - JANUARY 04:  Irish musician Sinead O'Connor seems to have quickly changed her mind about divorcing her 4th husband, Barry Herridge.  Earlier today, Sinead tweeted that her and her new husband are back together.  The pair were spotted taking in the Greenstar bins at her home in Bray, Co. Wicklow. Sinead was more than happy for the photographers to snap pictures of the smile on her face, while Barry looked more serious and downcast.    on January 4, 2012 in Dublin, Ireland<br />
