It originally aired on Fox in the United States on May 3, 2009.
The Griffins learn that Brian's ex-girlfriend, Jillian, is getting married to "the perfect man in every aspect", Derek.
Peter has been asked to walk Jillian down the aisle, and the others are invited except for Brian.
Drew Barrymore returned as Jillian, and Lauren Conrad and Audrina Patridge guest starred as themselves.
In her second guest appearance on the series, Conrad played a smart version of herself, which she proclaimed as being fun to play.
