According to Xpose on Sunday, David is said to be missing Rocco in his life after the teenager refused to board a plane from London to New York City to spend Christmas with his mother Madonna. He's been living in the British capital with his father Guy Ritchie and his family for several months now.

One source close to the situation said, "Everybody is talking about Madge and Guy 's fight over Rocco - but there's much more to it. The dispute is hard on the whole family, and David is really feeling it. David very much looked up to Rocco in that big brother role."

In fact, many sources close to the chart topper say she's taking the case especially hard now that she no longer has her son near her.
