One very fashionable wedding! Designer Christian Siriano married his fiancé, Brad Walsh, in a romantic ceremony in Danbury, Connecticut, on Saturday, July 9.

The former Project Runway champ and his groom wore black for the white-themed nuptials, which were officiated by actress Kristen Johnston.

The 3rd Rock From the Sun alum posted a pic before the outdoor ceremony along with the caption, "About to start the most beautiful wedding ever."

Earlier in the day Siriano, 30, tweeted a pic that showed him holding a silver bag embossed with the word "Fabulous."

The 150 wedding guests included Kelly Osbourne, who said the designer was the only one she would wear all-white for, and Jay Manuel, who shared a pic of the grooms being serenaded by Danielle Brooks from Orange Is the New Black.

New York City caterer Certé provided the decadent dishes for the wedding, which included one of Siriano's favorite foods — lobster. After the couple cut the cake, Siriano asked his new husband not to smush cake into his mouth (watch the Instagram video below to see what happened next).

The designer, who won season 4 of Project Runway in 2008, and his musician boyfriend announced their engagement in July 2013, exchanging engagement bracelets instead of rings.

Siriano, who has dressed stars including Jennifer Lopez, Sarah Hyland and Zendaya, recently teamed up with Leslie Jones to create a dress for her to wear to the Ghostbusters premiere.

He came to the Saturday Night Live star's rescue after she tweeted about her frustration at not being able to find a designer to dress her because she isn't a size 0.

After getting praised on Twitter for it, he tweeted, "It shouldn't be exceptional to work with brilliant people just because they're not sample size. Congrats aren't in order, a change is."
