Break out the baby bottle! Nick Lachey and wife Vanessa Lachey are expecting their third child together, the duo announced on Friday on Instagram.

"#LacheyPartyOf5... and Wookie!," Nick captioned a cute photo that shows the family outside of their home with moving boxes. The parents raise their arms in the air in celebration while Vanessa cradles her bump. A heart is seen around her belly.

"We got a new crib! Now we need a new CRIB," the message reads across the top of the image.

Vanessa shared the same photo to her Instagram that said that "newest Lachey arriving Spring 2017."

The Lacheys recently moved into a 7 bedroom, 10 bath home in Encino, California, that once belonged to the late singer Jenni Rivera, so they have plenty of room of the new family addition.

Nick and Vanessa married in 2011 and are also ready parents to Camden John, 3, and 8-month-old Brooklyn Elisabeth.

In June, Vanessa didn't rule out the possibility of having another child.

"The second [child] has been different just in the sense that it's nonstop, but I love that," she told E! News. "It's busy and it's chaotic, but...it's what I've wanted and it's all I know right now and on top of all of that, I have the most amazing supportive husband.

"If we're blessed with no. 3, it's just going to be that much more exciting," she added. "If it happens, it happens!"

The couple often shared photos of their children on their respective social media pages.

When her daughter was born, Vanessa gushed about being a mother for a second time.

"I have been dreaming of this moment for as long as I can remember, the day I was going to meet my little girl. A friend recently told me how magical today was going to be because it's the day I would meet my best friend," she wrote on her blog. "I can't even begin to tell you how it felt to hold her in my arms for the very first time. Mommy, Daddy and big brother Cam love you so much already, Brooklyn!"

Now, they're all about to spread a little more love around for another little one.
