Baby Girl on the Way for Nick and Vanessa Lachey

Nick and Vanessa Lachey have (another) one on the way!

The couple, already parents to Camden John, 22 months, are expecting their second child — a daughter, Nick announced via Twitter Tuesday.

“Can’t think of a better way to celebrate 3 years of marriage to my beautiful Vanessa than this,” the singer wrote, sharing a photo of Camden running on the beach around a heart in the sand that reads, “It’s a girl.”

While the pair decided to wait until their firstborn was older, it was only a matter of time before the VH1 host, 40, and his wife, 33, expanded their brood.

“We’re incredibly blessed,” Lachey told PEOPLE in November, calling parenthood “the most amazing experience you could ever go through.”

And it looks like the doting dad’s dream of a daughter is coming true.

“I do want a girl. I think there’s something emotional about having a daughter that I definitely want to experience,” he told PEOPLE in February.

“Maybe I’ll get one more boy under my belt first. I’ll need some help to keep her in line, so a couple of brothers couldn’t hurt.”
