Barron was photographed on Wednesday, July 7, exiting Trump Tower in Manhattan and standing considerably taller than the 51-year-old.
The former first son wore a dark long-sleeve top tucked into jeans and carried his mother's bag for her.
Last month, former President Donald Trump marveled at his son's height at a North Carolina GOP convention. "Barron is 6-foot-7, can you believe it?" the proud papa, 75, said. "And he’s 15."
"Eric is short — he’s only 6-foot-6," he joked of his 37-year-old son, who used to be the tallest Trump. Meanwhile, Melania stands at 5-foot-11 inches and the Celebrity Apprentice alum is said to be 6-foot-3.
Barron is rarely in the limelight or photographed, which may be why people were so shocked to see his growth spurt.
Since leaving office, the former first family relocated to Trump's Mar-a-Lago resort in Florida. Since the resort closes in summer, Trump has reportedly been staying in Bedminster, NJ.
