Victor Garber is married! The 66-year-old "Legends of Tomorrow" actor said "I Do" to his longtime artist boyfriend Rainer Andreesen Saturday, confirmed ABC News. The two have been together for 16 years.

Andreesen made the announcement over the weekend on Instagram, posting a sweet photo of himself with his new husband. He captioned the snapshot: "YES WE DID! #justgotmarried #elopedintofino #canada @therealvictorgarber #after16years."

Garber posted his own photo with the caption: "Wickaninnish Inn Tofino BC magical place to tie the knot. @rainerarts."

The couple coordinated in black tuxes and gray ties for their big day.

Neither Garber nor Andreesen released any details about the nuptials.

The couple began dating in 1991. In 2012, Garber, who officiated Jennifer Garner's 2005 nuptials to Ben Affleck, opened up about some of his greatest achievements in life, which he admitted included his relationship with Andreesen. The interview was also the first time Garber publicly acknowledged his relationship with the model/artist.

"My companion Rainer Andreesen and I have been together almost 13 years in Greenwich Village. We both love New York," he said during the interview with Canada's Forever Young News.

Congratulations to the newlyweds!
