Danny LeClair, 45 and Aubrey Loots, 42, from Los Angeles, will celebrate their wedding atop a float at the historical Tournament of Roses Parade, the Pasadena Star-News reported.
The Tournament of Roses Parade began in 1890. This year, the famous festival of flower-covered floats will be watched by an estimated 500,000 people and millions of television viewers.
Leclair and Loots' wedding will take place atop a huge, elaborate wedding cake-shaped float which is sponsored by the AIDS Healthcare Foundation. The float's theme is "Love is the best protection."
This is the first Rose Parade to take place since the Supreme Court's ruling in June brought marriage equality to California.
The couple also started a social media experiment around their wedding asking people to publicly declare their love for others using the hashtag #loveexperiment during the Rose Bowl Parade.
The couple, who met 12 years ago at an L.A. nightclub, had a commitment ceremony 10 years ago. Leclair applied to be part of the AIDS HealthCare Foundation float at a wedding expo earlier this year.
Leclair told the Pasadena Star-News:
"One of the things we're really excited about is we're standing on the shoulders of thousands of men and women who came before us in this fight for marriage equality. We're excited to be part of that story, to be able to do this because of them. We're looking forward to honor that."
