"Katie and I got married last night, we wish you all could've been there," the singer-songwriter told his more than 300,000 followers. It was magical! Love, Neil. The couple - he's 71, she's 42 - tied the knot in L.A. in front of friends and family, his rep told People. It's McNeil's first wedding, and the third for Diamond, who was previously married to high school sweetheart Jayne Posner, then to Marcia Murphey. Diamond and Murphey were divorced in 1995. He has two daughters from his first marriage and two sons from his second. McNeil, who executive produced the 2009 TV documentary "Neil Diamond: Hot August Night/NYC," is her new husband's manager. The music legend, a 2011 Kennedy Center Honors recipient, will launch his 2012 tour on June 1 in Fort Lauderdale, Fla., coming to L.A.'s Greek Theatre for a number of performances beginning Aug. 11.
