People Magazine has the story:
Louganis, 53, married paralegal Johnny Chaillot, 52, Saturday evening at Geoffrey’s in Malibu. “It was amazing because I have so many people from all facets of my life here tonight and they are all here and celebrating it is all wonderful,” Louganis told PEOPLE immediately following the sunset ceremony. “I already feel different. The ceremony was so reflective and representative of who we are.” The recent Splash coach and Chaillot began dating in 2012 after finding each other on the online dating site Match.com and became engaged almost exactly a year later on April 8.
In lieu of gifts, the couple asked for donations to charities.
