James McCartney has revealed he "didn't really like" his father Sir Paul McCartney's ex-wife Heather Mills. The 35-year-old musician and the charity campaigner never saw eye-to-eye throughout Heather's marriage to Paul - which ended acrimoniously in 2006 before they eventually divorced in 2008 - and he partly blames her for his estrangement from his dad. Speaking to the Daily Mirror newspaper, James said: "It was a difficult time. Dad was married to Heather and we didn't get on. I was so into Kurt Cobain and this mentality so I didn't really like her. It was very difficult, I had my own issues ... The estrangement was partly because of Heather. It was difficult because of mum's death and then moving on, having a new mother. We drifted quite far apart, it was a difficult period. I had to strike out on my own and I needed a bit of time to grieve my mum's death ... I started getting more into Class A drugs, ketamine. I wasn't doing heroin. At the time I severed that tie with the rest of the family a little bit which I wish I hadn't done now." James eventually sought treatment for his substance abuse problems and got clean and started to repair his relationship his Beatles star father.
