Oh no! Harper Beckham is the only one of soccer legend David Beckham's kids who still shares his passion for playing soccer.

On Friday's episode of "The Graham Norton Show," the sports icon revealed that Brooklyn, 19, Romeo, 15, and Cruz, 13, have all moved on from the sport, leaving only Harper to follow in daddy's footsteps.

"She loves it," the father of four beamed, explaining how his 6-year-old daughter plays every Sunday. "The boys don't play anymore, which is heartbreaking."

The proud daddy added that he's only joking about the heartbreak part -- "It's not really," he said -- but his tone sounded as if he really does miss his boys kicking the ball around.

"They have a talent, but obviously none of them play anymore," he continued. "So, it's down to Harper."

The soccer star, 43, admitted that he can get a bit "enthusiastic" when rooting for his daughter from the sidelines. And, of course, he's a bit protective of his little girl, telling a tale of when he didn't know how to react when another player, a boy, ran into his girl during a match.

"I was looking around at the other parents thinking, 'How do I react?'" he joked. "Do I be a UNICEF ambassador… or do I be Harper's daddy and be like, 'Really?' So, I just let it go."

Looks like Harper's enthusiasm for the sport goes back a few years. In 2015, the proud papa posted a photo of her at age 3, shooting a goal.

"Mia Hamm eat your heart out. Harper taking lessons from her brothers (oh and her dad)," he wrote in the caption.

They may not be playing dad's favorite game, but talent appears to run deep in the Beckham household. Brooklyn has a strong interest in photography, having shot campaigns for Burberry, and Romeo likes tennis, whereas Cruz is a music person -- a guitar player.

Here's to Harper keeping the family tradition alive!
