Neil Diamond is once again a married man. "People" magazine says the singer-songwriter and his girlfriend Katie McNeil tied the knot in a ceremony in Los Angeles over the weekend. Diamond's rep says family members and close friends were on hand to witness as the couple exchanged their vows. The wedding follows a seven-month engagement. Diamond announced back in September that he had proposed to Katie, who's also his manager. Saturday's event marked the 71-year-old star's third trip down the aisle. It's the first marriage for his 42-year-old bride.
