His iCarly besties Miranda Cosgrove, Jennette McCurdy, and Jerry Trainor showed up to support him (and even carpooled together). Plus, Doug Brochu, who played Duke on a few episodes of the show, was one of the ushers. So basically, this joyful gathering was like one big reunion! And their wedding hashtag, #SayYesToTheKress, is as adorable and hilarious as you'd expect.
Beyond the typical wedding cuteness, their special day got even more romantic. Remember the car from Nathan's proposal? He apparently bought it from London's grandfather so they could drive off from the wedding in the same car that her parents did. And that they did!
