Couch owners are on high alert this morning amid news that Tom Cruise and Katie Holmes are engaged. At a news conference in Paris Friday morning, Cruise confirmed that he popped the question to his scuba-diving partner just hours earlier, high atop the Eiffel Tower. "Today is a magnificent day for me," he said. "I'm engaged to a magnificent woman." No wedding date has been set: "We haven't discussed that," Cruise added. "One step at a time." Yeah, the last thing they want to do is rush things.
