Angelina Jolie spends much of her time "alone" when she's not busy raising her children

Angelina told The Sun newspaper: "I have my children I love but as an adult I'm often alone. I find myself identifying with the solitude and loneliness [Maria] has.

"I also haven't quite figured out how to live life in a way where I'm on my own. Maybe a lot of artists feel that we're in an open space as a person. We don't quite settle. So it leaves us in a strange way sometimes."

It comes after the 'Maleficent' star insisted looking after her children is way more important than anything else in her life.

During an appearance on 'Good Morning America', Angelina spoke about her role in 'Maria' and was asked if there's anything in her life that compares to the late star's love of singing and the actress replied: "My motherhood ... It's my happiness. You can take everything else away from me ... Nothing else matters."

Maddox and Pax have been working behind-the-scenes in the movie industry while Vivienne recently helped her mother put together Broadway show 'The Outsiders' but Angelina is adamant none of her kids want to be in the spotlight.

She explained: "None of my children want to be in front of the camera at this time. They are quite private. Shiloh's extremely private. They weren't born with privacy, right? So I hope they can have that as they grow."

Angelina previously won an Academy Award for her role in 1999 psychological thriller 'Girl, Interrupted' and she's currently gaining Oscar buzz for 'Maria' but the actress is adamant she's already had her reward by working with such a great team on the film.

When asked about the Oscar buzz surrounding the film, she laughed to Best UK magazine: "It means a lot that somebody thinks you did a good job. Right? That means everything to me.

"That kind of stuff is exciting and very, very nice. But I'm just so happy we were able to do this film. I'm genuinely so happy.

"I know it sounds like people say this, but really, this was an experience of a lifetime. I learned to sing and I embodied a woman that I respect. I was able to work with this extraordinary team of people.

"I feel like I've already been given the greatest gift. The audience seemed to respond well to it. So, anything else is a dream, but I'm so grateful already."
