Brandy craves an extended family with her daughter's father Robert Smith - just like the one Demi Moore and Bruce Willis juggle successfully.

Now married with three kids, Smith has moved on from his romance with the singer, but Brandy is determined to make sure they remain friends.

She says, "I remember calling him up and saying I saw this picture of Demi Moore and (her ex-husband) Bruce Willis and (Moore's current husband) Ashton Kutcher and all the kids at a red-carpet event, and I said, 'We should be like that.'

"He said, 'You know what, B? We're just one big family.' It feels good to have a situation like that because it could be drama."

Brandy and producer Smith split in 2003 after a fake marriage and divorce, they have a six-year-old daughter, Sy'rai, together.
