Barron Trump may share his father Donald Trump's love of boxing.

The 18-year-old -- who the former president shares with wife Melania Trump -- was spotted showing a rare smile as he watched boxing star Ryan Garcia show off his fast hands at Trump's Mar-a-Lago residence in Florida last week.

A video posted on Garcia's Instagram Friday night showed Barron looking dapper in a black suit and white shirt as he grinned at the 25-year-old pro's shadowboxing skills.

As seen in the now-viral video, Barron was joined by several others, including his father, who also smiled at Garcia's display.

Garcia, who won against Devin Haney in a huge upset just days before posting the video, called the GOP 2024 presidential candidate a "friend" and endorsed him.

"TRUMP IS MY FRIEND. Have a great day," the boxer captioned the video. "TRUMP 2024."

"Barron Trump ... is so freaking handsome!" one TikTok user commented.

Another person claimed Barron looked "league ready" due to his impressive height of 6 feet and 7 inches.

One user wrote on X: "Barron's smile stole it. He's just such a damn good looking kid."

Another fan said she "loved seeing Barron standing there all happy."

"Barron Trump in the back, towering over everyone," a third X user observed.

Even Garcia could not help but comment on Barron's height, calling the teen the "tallest man alive" on X.

Meanwhile, some fans suggested that Garcia should give Barron some boxing tips.

"If you coached Barron on how to fight, he would be a force of nature. Secret service would be asking him for backup," one person commented on Garcia's post.

Barron's father is known to be a longtime boxing fan.

Trump was inducted into the New Jersey Boxing Hall of Fame in 2015 due to his role in establishing Atlantic City as the capital of the boxing world in the 1980s, according to Fox Sports.

"Donald Trump was very good for boxing in New Jersey," New Jersey's longtime boxing commissioner Larry Hazzard said, The Philadelphia Inquirer reported in 2017.

After leaving the White House, the real estate mogul provided commentary for a 2021 exhibition match headlined by boxing legend Evander Holyfield.

It is unclear if Barron is also a fight fan, but Trump has described his youngest son in interviews and rallies as a good athlete who loves soccer.
