Lizzy Caplan and Tom Riley

Lizzy Caplan and Tom Riley tied the knot in Italy over Labor Day weekend, People reports. Riley, an actor and producer, posted a black-and-white photo of the couple at the exciting event on Instagram on Monday, writing, "This one seems fertile. She shall make a satisfactory first wife." In the pic, Caplan and Riley are sitting on the ground and laughing, still in their wedding garb: a slim-fitting suit and patterned tie for Riley and a dreamy, long-sleeved gown and flowery hairpiece for Caplan.

This is far from the first photo Riley has shared of his new wife on Instagram. Earlier this year, he and Caplan attended the Women's March in Washington, D.C., after which he posted photos of the signs they carried, reading "Keep your filthy paws off my silky drawers" and "Not my president (literally)." And in June, in honor of Caplan's 35th birthday, Riley, 36, penned a hilarious note to his then fiancée alongside a photo of the duo holding hands and cracking up on a red carpet. "Happy Birthday to my forever mancrush Monday. A girl whose fake laugh game humbles and inspires me. She was truly miserable in this picture but you would NEVER KNOW and it’s that kind of ability to suppress emotion that will serve us well in our life together. #mcm," he wrote.

The pair, who met in early 2015 and made their red carpet debut as a couple in February 2016, got engaged in May 2016, although they didn't confirm the happy news until several months later. And although their proposal and the engagement ring were fairly traditional — Riley popped the question with a round-cut diamond set atop a rose gold band — Caplan has previously said that she has no intention of stepping into the "traditional" role of the stay-at-home mom anytime soon. "I actually romanticize the idea of a stay-at-home dad," she told Elle Canada in 2014. "Partly because I think that's a very sexy thing, but also because if there are two working actors and both of them get a job and they have a baby, the woman is going to stay with the baby. I see it all the time. It just seems unfair. I don't want it to be an assumption that I will be the one to stay home and raise the kids."
