Victoria Beckham is keen to have another baby - and is desperate for a girl, it has been reported.

The wife of football star David Beckham is hoping to get pregnant again later this year after the World Cup in South Africa.

Posh Spice, who is now a fashion designer, already has three sons with her husband.

But she's said to have become even more broody since her younger sister Louise has become pregnant with her fourth child.

Victoria and David are reportedly desperate to have a baby girl.

They do know you don't get to choose, don't they? Although with the amount of cash they've got floating around, perhaps it's an option.

Hollywood actress Renee Zellweger is thinking twice about motherhood after babysitting for her niece and nephew.

Renee says parenting is like "slavery" and babies are "little dictators". Sounds like she's got it about right...

The Bridget Jones star said: "Moms out there, kudos to you. The cool thing about being an aunt is like, I can leave. No offence to my big brother Drew, but that is slavery.

"I dare you to take a shower. You can't do anything unless they let you. It's a dictatorship. They're little dictators in their crib."

The star, who's 40, hasn't ruled out having children but she's obviously got a realistic grasp of what it might be like.

Every baby is a blessing, and whether you have a boy or a girl is just a random, unpredictable twist of fate, right? Well, not necessarily, as new research claims that there are definite biological reasons which determine that wealthier women are more likely to give birth to boys, whilst poorer women are more likely to have girls.

So it's no accident that Victoria Beckham has ended up with her three boys Brooklyn, Romeo and Cruz. Her bank balance meant it was always going to be so.

Here's the science behind the theory:

It's been widely reported that they are "desperate" to have a little sister for their boys Brooklyn, Romeo and Cruz.

So how is that poor child going to feel if he turns out to be another little boy?

Therapists' couches are full of people who are convinced that the root of their problems is that their parents wanted them to be the opposite sex.

I'm lucky – my parents already had two boys and were delighted when they had me.

But that can create other problems too. I don't think a football-playing, sports-mad, tree-climbing, holey-jeans-wearing tomboy was quite what they had in mind. They couldn't get me to wear a dress however much they tried.

That's the thing about children. They can always confound your expectations.
