After seven years of marriage, it's over for Jennifer Lopez and Marc Anthony. "We have decided to end our marriage," they tell PEOPLE in a joint statement. "This was a very difficult decision. We have come to an amicable conclusion on all matters." "It is a painful time for all involved," the statement continues, "and we appreciate the respect of our privacy at this time." Lopez, 41, and Anthony, 42, wed in June 2004 in a casual and secret ceremony at Lopez's Beverly Hills home.
