Mark Ronson once had a sleepover at Michael Jackson's house.
The DJ-and-producer, whose stepfather was Mick Jones from rock band Foreigner, moved to the US as a child and became friends with Michael and John Lennon's son Sean.
Ronson revealed: "I had a sleepover with Michael Jackson once. I haven't seen him since. He doesn't call, he doesn't write."
The 29-year-old music star - who DJ-ed at Tom Cruise and Katie Holmes' wedding and has spun records for P. Diddy and Prince - admits he decided to stop playing at celebrity parties so he would be taken seriously as a producer.
Ronson said: "The fashion crowd discovered me and I was suddenly an 'overnight sensation.' The term celebrity DJ was almost invented for me. It was annoying and I couldn't wash it off. I realized I would have to stop if I wanted to be taken seriously for my music. I'd get calls saying, 'Will you DJ the Martha Stewart Christmas party?' and there would be this voice in my head going, 'What would LCD Soundsystem's James Murphy do? Would he say yes? Probably not!'"
