Al Pacino, 83, demanded paternity test, didn't believe he could get ...

Al Pacino reportedly didn’t think he could get Noor Alfallah pregnant because of a medical issue that typically causes infertility.

Sources close to the situation claim that Pacino, 83, didn’t believe he was able to impregnate his 29-year-old girlfriend, or anyone else, and demanded she get a paternity test to prove the child was his, TMZ reported Thursday.

The sources alleged that the “Godfather” actor had medical issues that would normally prevent a man from getting a woman pregnant.

Pacino reportedly had doubts that the baby was his and asked for a DNA test. Alfallah went through with the test, which proved that he was the father of her child.

The “Scarface” star apparently had no idea she was expecting until two months ago and was allegedly “shocked” when he found out he was going to welcome his fourth child.

Pacino’s rep declined Page Six’s request for comment.

News broke that Pacino and Alfallah were expecting a child together on May 30. TMZ reported at the time that she is eight months pregnant.

He and the ex-girlfriend of Mick Jagger first sparked relationship rumors in April 2022 when they were seen grabbing dinner at Felix Trattoria in Venice, Calif. But several insiders told Page Six that they had been dating since the COVID-19 pandemic.

“She mostly dates very rich older men … She has been with Al for some time and they get on very well,” our source had revealed. “The age gap doesn’t seem to be a problem, even though he is older than her father.”

It’s reportedly unclear whether the duo are still together, as a source claimed to gossip site Showbiz411 that they have “no relationship.”

The source alleged that Pacino “actually thought their relationship was over a long time ago” and has had “lawyers … working on this for months.”

Pacino already shares daughter Julie, 33, with Jan Tarrant as well as twins Olivia and Anton, 22, with Beverly D’Angelo. Meanwhile, this appears to be Alfallah’s first child.

His “The Irishman” co-star Robert De Niro — who just welcomed his seventh child with his partner Tiffany Chen — shared his support for his Hollywood pal.

“He’s a few years older than me,” 79-year-old De Niro told Hoda Kotb on the “Today” show Thursday, adding, “God bless him.”
