The couple already have four children
Brad Pitt's manager has denied reports that the actor's partner Angelina Jolie has given birth to twins in France.
"It's not true, it's a rumour," Cynthia Pett-Dante told news agency Reuters.
US show Entertainment Tonight reported on Friday that the actress had given birth, quoting an unnamed person close to the actress.
The 32-year-old confirmed she was expecting twins at the Cannes Film Festival last month after weeks of media speculation.
However several celebrity news outlets reported the story was false.
People magazine quoted an unnamed representative for the actress on its website as saying: "Angelina has not given birth. She is fine, enjoying her home and her family in France."
The only maternity clinic in the southern French city of Aix-en-Provence, the region where Jolie and Pitt were believed to be staying, said it had no information.
Pitt and Jolie reportedly bought a $70 million (£35.6m) chateau in the French Riviera recently to base their growing family.
The couple have four other children - six-year-old Maddox, Pax, aged four, and three-year-old Zahara - who are all adopted, and two-year-old daughter Shiloh.
Britain's Now magazine has reported that the latest additions to the Jolie-Pitt family had already been named Isla Marcheline and Amelie Jane.
