Diddy: 'I don't know how marriage works'

Sean 'Diddy' Combs can never see himself settling down - because he lacked good married role models when he was young.

The Bad Boy Records boss has dated a string of beauties throughout his meteoric career - including Jennifer Lopez and model/actress Kim Porter, and had rumoured flings with Sienna Miller and Cameron Diaz.

But the father of six doesn't understand the ethics of married life and blames his single-parent upbringing with mum Janice, who was left to raise two kids after Combs' father Melvin was shot dead in New York.

He says: "I don't know how marriage works. If you're raised by a married couple, you see how they interact; their good days, their bad days, how they work through things - you see the love.

"I wasn't brought up like that and I still don't know to do it. I never saw (my parents') relationship up-close, so every time I've been in a relationship I haven't known what to do and that's really scared me."

The hip-hop star broke off his relationship with Porter just months after she gave birth to their twin daughters Jessie James and D'Lila Star in December 2006.
