Victoria might have the authority in the fashion department, but when it comes to daughter Harper's hair, it's David Beckham's domain.

In an interview for Yahoo Style, David Beckham said that he's asserted his authority over their daughter's hair when Posh Spice suggested that they cut it.

"You know, about a year ago, my wife said, 'Maybe we should cut Harper's hair,'" he said. "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."

"You saved Harper's hair!" the interviewer said.

To which the former footballer replied, "I had to. It's just so good, isn't it?"

But David Beckham can be forgiven for obsessing about daughter Harper's hair. After all, his mother was a hairstylist although she didn't pass that skill along to her son.

"I wish she did. I do cut my sons' hair from time-to-time. When they have a buzz cut, I do it. If I have to use scissors, the boys know not to ask-she never taught me how to do that," he added.

In the same interview, however, David Beckham acknowledged that when it comes to fashion, he takes a backseat to his wife.

"I trust her more than I trust my judgment!" 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.'"

In another interview with Entertainment Tonight, David Beckham admitted that his daughter Harper has her way around him.

"I have no power with that little girl - no power whatsoever," he said. "I love all my children, of course, equally but I'm definitely stricter with the boys than I am Harper, which gets me in trouble with my wife of course."
