In May, Ferguson told PEOPLE that Beckett already “loves to perform as well.”
“Maybe he caught the bug early,” Ferguson mused while at the Tony Awards nominees press event. “We’re starting him withSesame Street. We’ve shown him some videos of me performing. He’s excited to see me on stage. It’s exciting for him.”
The month prior, Ferguson shared a picture of Beckett in his stroller pointing up to a life-size photo of his dad outside the Helen Hayes Theater.
“Beckett isn’t sure why papa is all over this block in nyc,” Ferguson captioned the adorable snapshot.
“There is a lot of really horrible stuff going on in the world right now, so Justin and I wanted to share a little bit of good news with you,” Ferguson said. “We are expanding our family.”
They then hinted at his second child’s due date, stating that Beckett will become a big brother “this fall.”
