(CNN) — Jesse Tyler Ferguson's character on "Modern Family" isn't married yet -- but Ferguson is.
The actor, who plays Mitchell Pritchett on the hit ABC show, married boyfriend Justin Mikita in New York City on Saturday, his publicist confirmed.
The actor and the lawyer have been outspoken advocates for same-sex marriage and founded Tie The Knot, an organization which raises funds to aid marriage equality. Playwright Tony Kushner officiated at their ceremony.
Ferguson tweeted his happiness on Sunday.
"Never been happier. XO Goodnight!" the actor tweeted.
Now it remains to be seen if Ferguson's character on "Modern Family" will marry his longtime partner, Cam Tucker, played by Eric Stonestreet. Fingers crossed!
