Al Pacino's grown-up kids react to dad expecting a child at 82

Al Pacino didn’t see it coming.

According to reports, Al Pacino’s grown up kids are not thrilled at the prospect of their dad set to welcome another child at 82.

For the unversed, it was reported earlier this week that the actor is expecting his fourth child with his girlfriend Noor Alfallah, 29.

The report said that the pair “have no relationship,” and Noor didn’t even inform the actor of her pregnancy until she was 11 weeks in.

The news came as a shock for Al Pacino who demanded his girlfriend a paternity test to confirm if it was truly his child.

"She (Noor) knew Al didn’t didn’t want to have more kids, they have no relationship, it’s a mess... Lawyers have been working on this for months," a source told Showbiz 411.

“He (Al) actually thought their relationship was over a long time ago... When Noor Alfallah did come back in his life after a more than year break, my insiders say she told Pacino she couldn’t have children anyway due to a thyroid problem,” they continued.

The actor is already a father to a daughter Julie Marie, 33, with his ex-girlfriend Jan Tarrant and 22-year-old twins Anton and Olivia with ex-girlfriend Beverly D'Angelo.

"The kids are very upset," the source claimed.
