David Beckham has "no power" over his daughter. The retired soccer star believes he's a push-over when it comes to disciplining four-year-old Harper and is a lot "stricter" on his sons Brooklyn, 16, Romeo, 13, and Cruz, 10. 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 40-year-old hunk previously admitted his fashion designer wife Victoria, 41, whom he has been married to for 16 years, is the "strict one in the house." However, they both keep a watchful eye over their eldest son Brooklyn and are able to "control" everything he posts on his social networking sites. He explained 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 and carve out a career in sport, but only if it's what they want to do and are happy doing so.
