Erin Lichy's family circus is XDY Exchangeexpanding.

The Real Housewives of New York City star is pregnant with her and husband Abe Lichy's fourth child, she on confirmed Nov. 12.

"It feels like adding another act to the circus," Erin—who is already mom to sons Levi, 9, Elijah, 4, and daughter Layla, 7—joked in an interview with People magazine. "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. Three vs. four kids doesn’t seem so scary."

The real estate agent also recounted the moment she realized she was expecting.

"I was out East with Abe and some friends when I suddenly became super sensitive to smells around me. That’s when I knew," Erin, 37, shared. "I thought, ‘Damn. Here we go again!’"

And while she noted "the first 10 weeks were rough" having suffered from exhaustion and nausea, she's now indulging in her pregnancy cravings: "Pinkberry and Greek yogurt, Italian food and French fries."

The couple have yet to find out the sex of their baby, but they are already narrowing down their favorite names.

As Erin shared they've "started floating around some name ideas, but we haven’t landed on anything just yet.”

Erin's exciting news may come as a surprise to RHONY fans, as she and her costars were seen gossiping about another cast member's possible pregnancy in the season 14 trailer.

"She had this wild night," Erin told Jessel Taank in the preview, "and ended up getting pregnant by some other guy."

See the pregnancy gossip play out when The Real Housewives of New York City airs Tuesdays at 9 p.m. on Bravo.
