The couple, already parents to Camden John, 22 months, are expecting their second child â€” a daughter, Nick announced via Twitter Tuesday.
â€œCanâ€™t think of a better way to celebrate 3 years of marriage to my beautiful Vanessa than this,â€ the singer wrote, sharing a photo of Camden running on the beach around a heart in the sand that reads, â€œItâ€™s a girl.â€
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.
â€œWeâ€™re incredibly blessed,â€ Lachey told PEOPLE in November, calling parenthood â€œthe most amazing experience you could ever go through.â€
And it looks likeÂ the doting dadâ€™s dream of a daughter is coming true.
â€œI do want a girl. I think thereâ€™s something emotional about having a daughter that I definitely want to experience,â€ he told PEOPLE in February.
â€œMaybe Iâ€™ll get one more boy under my belt first. Iâ€™ll need some help to keep her in line, so a couple of brothers couldnâ€™t hurt.â€
