Erin Lichy is celebrating the latest addition to her family tree.

The Real Housewives of New York star—who is also mom to sons Levi, 9, Layla, 7, and Elijah, 4, with husband Abe Lichy—recently announced the couple has welcomed their fourth child together, a baby boy.

“Jack Hunter Lichy,” Erin captioned her March 30 Instagram post featuring photos of her cradling their newborn, as well as a photo of the pair with all four of their kids. “#CrazyInLove.”

The Bravo star’s baby news comes four months after she opened up about her pregnancy, joking that it felt like “adding another act to the circus.”

“Work and life have been so busy that I haven’t really had a chance to even think about how it’ll change things, but I think it will be pretty seamless to be honest,” she told People in November. “Three vs. four kids doesn’t seem so scary.”
