Penn Badgley, musician and actor best known for playing sardonic writer and secret gossip monger Dan Humphrey on the CW's Gossip Girl from 2007-2012, is officially spoken for: Badgley married his girlfriend Domino Kirke at a courthouse in Brooklyn, New York on February 27.

Kirke is a musician and a doula (her work with expectant mothers was featured in a New York Times article from 2015), and she's also the sister of GIRLS star Jemima Kirke and Lola Kirke, star of Amazon's Mozart in the Jungle.

Both actresses congratulated their sister on social media after the low-key ceremony.

"When someone gets married in a courthouse, it's really an open invitation to everyone but the beautiful bride to explore all that fashion has to offer," Lola wrote on Instagram. "Here, I try a look simply called 'Pants,' as Cassius goes for 'That Dude from #incubus' and Jemima experiments with 'Off to Therapy!' Congratulations @dominokirke. We love you."

"Congratulations ya s---heads! @PennBadgley and @DominoKirke it's all downhill from here. In a good way," Jemima, who is married with two children, wrote on Twitter. She added, "to clarify they're married. domino badkirke. Penn kirkley."

Badgley starred in the drama The Paper Store in 2016, and is the frontman of a (pretty decent) indie electro band called MOTHXR. He dated Gossip Girl costar Blake Lively for several years.
