Sir Elton John doesn't want his mother in his life. The 'Rocket Man' singer - who has sons Zachary, four, and Elijah, two, with husband David Furnish - has been estranged from Sheila Farebrother for seven years and though he looks after her financially and sent her flowers for her recent 90th birthday, he isn't interested in having more contact with her. He said: "It upsets me, but to be honest with you, I don't miss her. "When she says things in the press, like last year: 'I haven't spoken to Elton since he married that f***ing asshole David Furnish...' That was pretty hard to take. "I don't hate my mother. I look after her, but I don't want her in my life." The 68-year-old singer had a difficult relationship with her father Stanley Dwight - who died in 1991 - and even now is still desperate for the former RAF officer's approval. He told Rolling Stone magazine: "They wouldn't hold you, they wouldn't say they loved you. "I was afraid of my father. I was walking on eggshells the whole time trying to get his approval. He's been dead for a long time, and I'm still trying to prove things to him. "I still do things and say, 'Dad, you would've loved this.' " The 'Benny and the Jets' singer was beaten by his father when he was younger and is still "affected" by their altercations. He added: "My mum always says, 'That's just the way we did it in those days, and it didn't affect you.' "And I'd say, 'What are you talking about? It affects me every day.'"
