Time has flown by! We can't believe it's already been two years since we saw Prince William and Catherine Middleton walk down the aisle at Westminster Abbey and say their "I Dos." And their lives (and ours!) haven't been the same since: The gown Kate wore by Sarah Burton for Alexander McQueen became a museum piece, her maid of honor Pippa Middleton shot into the spotlight thanks to her backside that very day, the Duchess became a style icon with her her every move tracked (and eventually selling out), and finally, the love keeps going now that the blissful couple now have a baby on the way. But it all started April 29, 2011. Click through the gallery to remember the glorious day.
