Irish actor-turned-Hollywood heartthrob Colin Farrell plans to attend a celebration to mark the recent wedding of his brother, Eamon Farrell (pictured right with Colin), to his artist husband, Steve Mannion. The Irish Independent reports that the couple was married this summer in Canada, with Colin serving as best man for his brother. The party in Dublin on December 27 will mark the pair’s official Irish wedding bash. Farrell’s mother, Rita, and sisters, Claudine and Catherine, are scheduled to attend, as are many Irish celebrities.
