Following 18 years together, Mark McGrath and Carin Kingsland made it official on Sept. 24, tying the knot in an intimate ceremony featuring just 70 guests at San Ysidro Ranch in Santa Barbara, Calif. "It was such an incredible day," said the bride, who wore a gown from Renée Strauss's bridal boutique in West Hollywood, while McGrath donned a Hugo Boss suit.
