The widow of the Broadway star shared a video of the precious moment on Instagram, including a caption on how the milestone involved her late husband.
"Elvis said his first words today!! Listen closely!" she wrote. "He pointed at Nick in our new picture light and said 'right there.'"
"He hasn't seen Nick since March 30th," the fitness trainer continued. "The fact that he still knows who his Dada is, point to him and give him a kiss to me is amazing."
In the clip, the son of the late Broadway star is asked "where's dada" before he leans forward to kiss a photograph of his father and answer, "right there."

The moment comes weeks after Nick Cordero died at the age of 41 on July 5, after facing complications from COVID-19 for three months
While hospitalized, he suffered from multiple infections, sustained lung damage, spent time in a medically induced coma and required a leg amputation, among other health issues.
Kloots has shared many tributes on her social media accounts for her late husband since his passing. She's also opened up on her grief journey.
"This is a long journey ahead and a down road I never thought I'd be on," she wrote in a post on July 12. "No one can tell me how to do it, I have to do it. I may do things right, I may do them wrong. There isn't a perfect way. One day, one step at a time. I have faith that God is leading the way and that Nick is our angel."
Kloots also recently announced that Cordero's final album, a live recording of a one-man show he performed in April 2019, will be posthumously released on Sept. 17, which would have been his 42nd birthday.
