David Beckham is ''stricter'' with his sons than his daughter.

The former soccer star believes he's a lot harsher with his discipline when it comes to his sons Brooklyn, 16, Romeo, 13, and Cruz, 10, but seems to crumble when he's forced to tell off his four-year-old daughter Harper for being naughty.

Speaking to 'Entertainment Tonight', he said: ''I have no power with that little girl - no power whatsoever.''

He added: ''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.''

However, the handsome sportsman, 40, previously admitted his fashion designer wife Victoria, 41, whom he has been married to for 16 years, is the ''strict one in the house.''

Although, they both ''control'' their eldest son Brooklyn's social networking accounts due to his safety.

He said earlier this month: ''Because our 16-year-old son, Brooklyn, has got like four million Instagram followers... we control everything he posts, everything he does, and it's the same with our other kids.''

Meanwhile, David is hopeful his children will follow in his footsteps embark on a career in sport, but is adamant he won't push them to do something they don't want to.
