New York Giants cornerback Jason Sehorn, 30, and former “Law & Order” actress Angie Harmon, 28, were married in Dallas on Saturday night, a little more than year after the football star dropped to one knee and proposed to her on NBC’s “Tonight” show. The couple wed in the Highland Park Presbyterian Church, Harmon’s hometown house of worship. The Dallas Morning News reported on Sunday that security was tight as guests — who included Giants coach Jim Fassel and his wife, Kitty, some of Sehorn’s teammates, and “Law & Order” costars Jesse Martin and S. Epatha Merkerson — had to present credentials in order to be admitted into the ceremony. A reception followed at the estate of banker Gerald Ford (no, not the ex-President). The newlyweds reportedly plan to live in Dallas, despite Sehorn’s having recently re-signed with the New York team.
