Camden Lachey is growing up!
The 4-year-old son of Nick and Vanessa Lachey started his first day of preschool on Wednesday, and looked like a total rockstar doing it!
Vanessa took to Instagram to commemorate the occasion with one adorable pic of Camden all geared up and ready to go.
"#RockOn Preschool! Love you, Buddy! 😍," Vanessa captioned the cute snap.
Camden and his little sister, Brooklyn, have been the stars of several of the former TRL host's latest Instagram snaps -- and who can blame her?
The two stole the show at the Lachey family vacation:
Got all jazzed up for memorial day:
And gave their dad the sweetest sibling sandwich:
And who can forget the Lacheys’ latest adorable Instagram post, announcing baby No. 3?
