KEY POINTS:
Rumours are gaining force that Angelina Jolie is pregnant.
The Oscar-winning beauty cancelled a lecture she was due to give at the UN-linked Pio Manzu centre, near Rimini, Italy, due to "personal reasons".
Italian newspapers claim the actress - who is a UN ambassador - had to pull out at the last minute because she had discovered she was expecting.
Jolie has been photographed this week on the set of her latest film, period piece The Changeling, wearing loose fitting tops and dresses.
The actress already has an 18-month-old biological daughter Shiloh, as well as three adopted children, Maddox, six, Pax, three, and two-year-old Zahara, with partner Brad Pitt.
Letizia Manjani, a spokeswoman for the Pio Manzu centre, refused to rule out a pregnancy.
She said: "Angelina cancelled last week. Due to her privacy I can't confirm her pregnancy, but I can say that the Italian newspapers are correct in their reports."
Angelina and Brad - who first met on the set of Mr. and Mrs. Smith - have made no secret of their desire to add to their family.
Brad recently revealed they were keen to welcome a fifth child into their family, saying: "We're ready."
The Fight Club star said fatherhood is "the most fun" he's ever had, although he is constantly sleep deprived.
He said: "It's the most fun I've ever had and also the biggest pain... I've ever experienced. I love it and can't recommend it any more highly - although sleep is non-existent!"
