It looks like Harper Beckham’s long hair won’t be getting a trim any time soon – and it’s all thanks to her famous dad David.

Harper, 4, has notoriously long (and gorgeous) brown hair. And Beckham, 40, recently revealed to Yahoo! Style that he refused to let his wife Victoria cut it.

"About a year ago, my wife said, “Maybe we should cut Harper’s hair.” And I was like, “No! We need to grow it. Do. Not. Touch.” Since she was born, we haven’t cut it. That’s why it’s pretty much down to her knees," he said.

The 40-year-old went on to take full credit for saving his daughter's hair that day: "I had to. It’s just so good, isn’t it?"

But don't worry about David and Victoria's relationship - the footballer went on to pay a loving tribute to his wife and the mother of their four children. "We’ve been together for 18 years, married for 16. We trust each other’s judgement on everything. I trust her more than I trust my judgement," he said.

"I’ve never turned around to her and said, “you don’t look good in that; change.” Frankly, it’s hard—very, very hard—for Victoria to look bad in anything. But there are definitely times when I’ve worn things and she’s said, “Nice try, go back upstairs," David continued.

There's no word on whether David intervenes with the hairstyles of his sons Brooklyn, Romeo and Cruz...
