Director Guy Ritchie's recent attempts to teach his son ROCCO to ride a bicycle backfired badly when the five-year-old ended up with a bleeding face.

The SNATCH film-maker was horrified after launching Rocco off on his first unaided bike ride unsuccessfully, but his son's pain couldn't compare to his terror of facing wife Madonna's wrath.

He shudders, "As I was releasing him, I thought to myself, 'Hang on, this is probably not what a sensible father should do.'

"Forty seconds later, as he tried to turn a corner, the howl of pain began. He got a nasty gravel rash on his face. There were big chunks torn in his flesh.

"I just put my hands up. I was scared because it looked so nasty."
