Less than a week ago, the Vampire Diaries alum shared a sweet selfie with her baby boy to celebrate his first birthday.
"My baby is 1!! Pretty cool that you can grow your own best friend. It’s been the shortest/longest, most epic year of my life. Shout-out to my legendary teammate @ajoblon. It’s all super easy from here, right??" Holt wrote on Instagram, seemingly teasing that they were expecting again.
