Friends star Jennifer Aniston has lashed out at reports that her split from husband and Hollywood heartthrob Brad Pitt was caused by her unwillingness to have children.

"That really pissed me off," Aniston said in an interview in the September issue of Vanity Fair.

"I've never in my life said I didn't want kids. I did and I do and I will. I want to have it all," she said.

In the interview, the Friends star spoke of her loneliness following the breakdown of her marriage, her enduring love for Pitt and her belief that she would one day meet the right man with whom to start a family.

Aniston, 36, and Pitt, 41, separated in January this year after 4-1/2 years of marriage. Three months later she filed for divorce.

"The world was shocked, and I was shocked," said Aniston.

Soon after their separation, photos surfaced showing Pitt vacationing with actress Angelina Jolie, 30, and her son. Pitt and Jolie met while co-starring in the action comedy Mr and Mrs Smith.

Asked whether she believed Pitt's statements that he never cheated when the couple were together, Aniston gave a guarded response.

"I choose to believe my husband," she said. "At this point, I wouldn't be surprised by anything, but I would much rather choose to believe him."

"Am I lonely? Yes. Am I upset? Yes. Do I have my days when I've thrown a little pity party for myself? Absolutely," she said, while adding that she had not lost her feelings for her soon-to-be ex husband.
