/ Source: TODAY

They've already got two adorable little ones at home, and now Nick and Vanessa Lachey have announced they're expecting baby No. 3!

The 98 Degrees singer and his television personality wife shared the big news on Friday with a clever pregnancy announcement each shared on Instagram.

The announcement featured a photo of the couple, who married in 2011, posing with their son, Camden, who turns 4 this month, and daughter Brooklyn, 20 months, standing atop a stack of moving boxes outside their brand-new L.A. home.

"We got a new crib! Now we need a new CRIB!" reads a bit of cheerful text splashed across the pic. "Newest Lachey arriving Spring 2017."

"#LacheyPartyOf5... and Wookie!" 35-year-old Vanessa captioned the photo, which shows her cradling her already-growing baby bump.

Of course, it's amazing news for mom and dad, but it's exciting for the kids, too. Vanessa told last year that Camden loved being a big brother to little Brooklyn.

"He had a little bit of an adjustment period because he was an only child for two-plus years and was like, 'Who is this little person who’s not going away?'" said the proud mom.

But once Brooklyn got old enough to laugh at her big brother's antics, things got way more fun.

"Now he’s interested because she’s responding. When he jumps, she laughs. When he tickles her, she laughs. When he falls, she laughs. So now he’s like, 'I’ve got an audience.'"

And the audience is about to get bigger.

Congratulations to all the Lacheys on their exciting news!
