Former Beatle Sir Paul McCartney has grown closer to his children through his current divorce battle with Heather Mills. MCCartney's children reportedly had a difficult relationship with Mills, and are glad to be back in their father's life since they split up. He says, "I'm going through great struggles. I have a lot of support, particularly from my family. "We're close, anyway, but when you go into something difficult, it does bring you closer."
