0228-rocco-ritchie-brooklyn-beckham-AKMGSI-03Madonna's gotta be thinking, "Rocco wouldn't have broken his arm if he were living with me."

The 15-year-old was hanging out in London with fellow celebuspawn Brooklyn Beckham. 

We don't know how Rocco messed up his arm, but we DO know Madonna has been privately griping about Guy Richie's permissive parenting. 

Rocco and Guy are due in court soon, unless Guy and Madonna are able to strike a custody settlement.
