On Friday, approximately 17,000 "trekkies" attended the Destination Star Trek London convention -- and two attendees definitely stood out from the crowd.
Reuters reports that Swedish couple Jossie Sockertopp, 23, and Sonnie Gustavsson, 29, tied the knot in a Klingon ceremony, complete with traditional Starfleet garb and Klingon phrases.
The bride and groom wore full Klingon makeup to their ceremony, which they conducted one day after their legal wedding ceremony in London. Check out the video above to see more from this Star Trek wedding.
