She certainly has her hands full running around after her six children, juggling her own film career with that of her partner’s, and travelling the world for her humanitarian work.

But despite her hectic lifestyle Angelina Jolie has revealed she could well fall pregnant with another child.

The actress, 36, spoke about the prospect of expanding her brood and told Marie Claire magazine: ‘Nothing planned at the moment, but we just don’t know. I could end up pregnant.’

The Land Of Blood and Honey director also spoke out about how her children like it when she and Brad are affectionate together.

She revealed: ‘If they see Mommy and Daddy in need of some private time ’cause they’re going to kiss and whatever, the kids get all giggly and happy. Because it gives them some security.’

The couple’s children, Maddox, 10, Pax, eight, Zahara, six, Shiloh, six, and Knox and Vivienne both three, would like their parents to get married, although perhaps not for the right reasons.

She explained: ‘They have mentioned it, yes. If you take it in an emotional way, you think, Ohhh, the children! They don’t feel secure enough! But then you think, Now, wait a minute: They think a wedding is a party with a four-layer tiered cake!’

In the interview the actress also confesses that there is one thing missing from her life - she doesn't have any female friends.

'It was nice for me to play with other girls; I don't really have girlfriends in movies, if you've noticed, ' she said.

'Well, I have a few girlfriends, I just... I stay at home a lot. I'm just not very social. I don't do a lot with them, and I'm very homebound.'

The actress, director and mother-of six, who looks stunning in a blue top and gold statement ring on the cover of the U.S. magazine, has previously bemoaned the fact that she really only chats with her partner, Brad Pitt.

'I'll talk to my family,' said the actress, 'I talk to Brad ... But I don't know, I don't have a lot of friends I talk to. He is really the only person I talk to.'

Angelina's reputation as the ultimate man-eater and husband-stealer may account for her lack of gal pals.

She famously fell for Brad when he was still married to Jennifer Aniston and her second husband Billy Bob Thornton broke off his engagement to Laura Dern to elope with his Pushing Tin co-star.

One of the few close female friends that is not deterred by Angelina's reputation is singer Gwen Stefani.

Earlier this year the A-listers were spied with Gwen Stefani getting together at Gwen's home in London for a fun-filled playdate .

'All of the kids are very close in age. They've attended each other's birthday parties and gotten together several times at each other's homes,' a source to Yahoo news at the time.

The pair have been friends since 1998. 'Somehow Gwen and I keep ending up pregnant at the exact same time,' Jolie has explained.

Best known for action films such as Lara Croft: Tomb Raider, Mr. & Mrs. Smith and Wanted, Angelina also reveals that she may want to move on from acting.

'I woke up one day realizing, God, I'm an actor,' she said, 'I don't think I intended to be an actor. I think my mother wanted it for me.

'I loved telling stories, and I enjoyed the profession, but is it too late to be something else?'

And Angelina credits Brad with helping her juggle her career with raising children.

She also opened up about her daughter Vivienne being a 'girly girl', divulging; 'She is so elegant and delicate. Vivi will pick flowers from the garden and put them in her hair.
'She likes to get her nails done and collects stuffed animals'

She added: 'It's very funny for me to have to buy all things pink and watch princess movies!'
'Knox' she says however, 'is very much a dude. Very physical, tough. He loves dinosaurs and swords.

She also gushed about her happiness saying: 'Brad has expanded my life in ways I never imagined. We built a family. He is not just the love of my life, he is my family. I hold that very dear.

'I suppose what I’ve learned from Brad is to be able to have the kind of family whose happiness and well-being comes before your own.'

'I’m very, very grateful to have such a loving family, and I wouldn’t have that without him.'

Speaking about the subject of her film Jolie said: 'I think it's still hard to understand what happened and how it could happen 40 minutes away from Italy in the '90s at the time Schindler's List came out.'

'Some of the very darkest sections of the film were conceived in Shiloh's art class; I was in the back waiting for the kids to finish,' she added darkly.

The Hollywood star has also revealed she plans to do another war film focusing on Afghanistan, where she made humanitarian trips to recently.

In the Land of Blood and Honey is is scheduled to be released in the United States on December 23.
