Vanessa has a bun in the oven!

The two, who have been married for 3 years and have son Camden, 2, are expecting another baby together.

“Can’t think of a better way to celebrate 3 years of marriage to my beautiful @Vanessalachey than this! #family,” Nick wrote on Twitter including a photo that announced, “It’s a girl!”

They have always aid that they wanted to expand their family.

The two adore their son, “The little man is out of this world,” Vanessa told E! News earlier this year. “His personality is coming out. He’s putting sentences together. He got his first haircut. I feel like next is college and girlfriends.”

Congratulations to the happy couple!
