Grey's Anatomy: Wedding in the Works for Season 6 Premiere?

Grey's Anatomy caught viewers off guard (sort of) by wrapping up the medical drama with a wedding the saw Izzie (Katherine Heigl) and Alex (Justin Chambers) tie the knot instead of Meredith (Ellen Pompeo) and Derek (Patrick Dempsey). Although Meredith and Derek have already taken their relationship further by declaring their own vows, some fans are still hoping to see the day when Meredith walks down the aisle. And word on the street is that casting directors are currently looking for actors to play guest roles for the season 6 premiere of Grey's Anatomy for what sounds like a possible wedding in the works.
