The littlest Lachey has arrived.

Nick and Vanessa welcomed a son on Wednesday, Sept. 12, they confirm to PEOPLE exclusively.

“We are incredibly proud to announce the birth of our beautiful baby boy, Camden John Lachey,” the couple tell PEOPLE in a statement.

“Born today at 6:54 p.m., he came into this world at 8 lbs., 9 oz. and 21 inches. Love has truly been redefined for both of us.”
