Angelina Jolie doesn't have any "girlfriends".

The Oscar-winning actress - who raises six children, Maddox, 10, Pax, right, Zahara, six, Shiloh, five, and three-year-old twins Knox and Vivienne, with partner Brad Pitt - admitted she is "not very social", as she prefers to stay at home with her family than go out partying.

She said in an interview with Marie Claire magazine: "I don't really have girlfriends in movies, if you've noticed. 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.

"I'll talk to my family. 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."

While the 36-year-old beauty explained the couple have no plans to expand their brood at present, she conceded she could "end up pregnant" at any moment.

Asked whether she and Brad are hoping to add to their family, Angelina said: "Nothing planned at the moment, but we just don't know. I could end up pregnant."
