Sinead O'Connor calls off divorce

Irish singer-songwriter Sinead O'Connor tied the knot with Irish therapist Barry Herridge on Dec. 8, 2011 (her 45th birthday) while sitting in the back of pink Cadillac in Las Vegas. "I've been married before, but I've never had my dream wedding in Vegas. I wanted to do it there because it's casual, quick, not religious and, most of all, very romantic," O'Connor said, according to Reuters. The couple met only a few months earlier when O'Connor solicited for a man on Twitter. This was O'Connor's fourth marriage.2011: Year in Review
