Paris Hilton wants "three or four children" with boyfriend Benji Madden.

The hotel heiress – who was introduced to her Good Charlotte rocker boyfriend when best friend Nicole Richie started dating Benji’s twin Joel – is already planning her future with the musician, and thinks he would make a fantastic father.

She said: "I definitely want three or four children. And soon - maybe a year or two."

Paris – who has previously dated stars including Rick Salomon, Nick Carter and model Jason Shaw – also revealed she is happier than she has ever been.

She added to People magazine: 'Benji and I just had our seven-month anniversary. We are just so happy."

Paris recently revealed she has recorded songs with Benji, adding the tunes are "happy and fun".

She said: "The songs are just being mixed right now and should be done soon. I've got a recording studio at my house in Los Angeles and so we've been working there every night. It's been fun. Our songs are just happy and fun dance music. It reflects what Benji and I are like together - happy and fun."

Christina Aguilera wants to show her son she is a 'super-b***h'.

The 'Dirrty’ singer – who gave birth to her first child with husband Jordan Bratman in January – insists becoming a parent hasn’t changed her attitude and she is looking forward to showing Max her feisty on stage persona.

She said: 'I’m not going to go down the safe route because I have had a child. Motherhood hasn’t changed me.

'It’s like the line in my new single, 'Keeps Getting’ Better’, says, 'I’m still a super-b***h.’ 'I want to be the best mom I can be but I also want to show my son who I am as a person, not just this woman who changes diapers and breast feeds.'

Christina is set to play the Africa Rising Festival in London this week and is looking forward to unveiling her new baby-inspired live show.

She added: 'This is my first concert since I had Max and I can’t wait for everybody to see the full Christina show. It’s an incredible balancing act being a mom.

'But he’s the inspiration behind my new music, my new sound and even my new look.

'It’s all about playfulness and having fun now.'
