— -- Nick and Vanessa Lachey are on lucky No. 3!

The couple announced today via Instagram that they are expecting their third baby in spring of 2017. The matching photos, posted to both of their accounts, show the family of four with a stack of moving boxes in front of their new home.

"We got a new crib! Now we need a new CRIB!" the text on the photo reads. There is a heart around Vanessa's stomach with "Newest Lachey arriving Spring 2017" written beneath it.

Vanessa's post included the hashtag, #LacheyPartyOf5 and even gave a shout out to the family dog, Wookie.

The littlest Lachey will be joining 20-month-old Brooklyn Elisabeth and big brother Camden John, who's now 3.
