Proud mama Vanessa Lachey posted a photo of son Camden, nearly 4, via Instagram Wednesday.

“#RockOn Preschool! Love you, Buddy!” the Truth Be Told actress, 35, captioned the image of her son’s first day of preschool.

With one arm in the air, Camden stood at the front door with a sign that read, “Camden’s first day of 4-year-old preschool, 9/7/2016.”

Last week, the Entertainment Tonight alum and her husband, 98 Degrees star Nick Lachey, announced their third pregnancy.

“Newest Lachey arriving spring 2017,” the cute couple captioned the pregnancy announcement.

The Lacheys are also parents to 19-month-old daughter Brooklyn.
