Al Pacino's ex-girlfriend Noor Alfallah has filed paperwork asking a court to grant her physical custody of their baby.

The pair - who have been linked since early last year - welcomed their little boy Roman three months ago but they are believed to have ended their relationship and now 29-year-old Noor has filed a petition to determine to the parental relationships and demand full physical custody of the child with “reasonable visitation” for 'The Godfather' star.

In the paperwork - filed in California and obtained by The Blast - Noor has agreed to give 83-year-old Pacino joint legal custody of Roman which would allow him to help make decisions on matters such as medical treatment, education and religion.

Also included with the filing was a voluntary declaration of parentage which was signed by both of them six days after the birth of their son.

Roman - who was born on June 6 at Cedar's Sinai Hospital in Los Angeles - is the actor's fourth child. He is also dad to 22-year-old twins Olivia and Anton Pacino with his former partner Beverly D'Angelo as well as Julie Pacino, 33, from his relationship with Jan Tarrant.

Prior to Roman's birth, the actor revealed he was looking forward to becoming a dad again and said having another child at this point in his life was "really special".

In a video obtained by the Daily Mail newspaper, he said: "It feels like it always will. It's very special, you know. I've got many kids. But this is really special coming at this time."

The 'Scent of a Woman' actor previously explained he "gets a lot" out of fatherhood and finds it "upsetting" not being involved in his children's lives. He told The New Yorker in 2014: "I'm responsible to them. I'm a part of their life. When I'm not, it's upsetting to me and to them. So that's part of the gestalt. And I get a lot from it. It takes you out of yourself."
