Now, the 6-foot, 9-inch Barron is all grown up and enrolled at New York University's Stern Business School where, despite his growing celebrity statue, he is apparently keeping a low profile.
The sound of his deep voice came as a surprise to those who had last heard Barron as an adorable four-year-old squealing in a squeaky Slovenian accent in a 2010 interview.
Very nice to meet you,' Barron, 18, said while standing beside his father at Mar-a-Lago and politely greeting guests, including UFC President Dana White.
Matt Damon's 18-year-old daughter Isabella has a lot in common with Barron.
Earlier this month, it was reported that Barron prefers to play video games rather than socialize with his peers.
