Arwen Expansion

This is from E! Online:

......it's likely that Gladdy (Galadriel) will appear in Film One, when she meets the Fellowship, and at the end of Film Three, for Aragorn (Viggo Mortensen) and Arwen's (Liv Tyler) coronation and the Grey Havens scenes.

Aragorn and Arwen's coronation?? Does this seem strange to anyone else? Could they be getting married before he is crowned?? Even Elrond says to Aragorn: "Arwen Undomiel shall not diminish her life's grace for less cause. She shall not be the bride of any Man less than the King of both Gondor and Arnor." Maybe the reporter meant to say wedding. Besides, Galadriel wasn't at his coronation. Have I missed something about how they are handling the wedding and/or coronation in the movie?
