Hollywood icon Robert De Niro smashed up a payphone at a New York diner after hearing Donald Trump had become the US president.

The 81-year-old actor was outside the diner, talking on the phone, when he learned that Trump had sealed a historic victory over Democrat Kamala Harris in the US presidential election.

Eyewitnesses claim De Niro broke down and started slamming the phone against the door of the phone box during an expletive laden rant.

The Raging Bull star then exited the phone booth and started kicking it until the booth fell over.

De Niro has long been an outspoken critic of Trump and is currently in the 8-year process of emigrating to Canada since the real estate magnate’s first presidential election success.

Paddy Power News has obtained a transcript of the telephone conversation between De Niro and an Italian American associate named Vinnie, which reads as follows:

De Niro: Who’s this? Vinnie? What happened?

Vinnie: We had a problem.

De Niro: What do you mean we had a problem? Kamala won, right?

Vinnie: We tried to do everything we could but Trump’s president. That’s it.

De Niro: (sobbing) I can’t f***ing believe it.

It follows reports that Trump took to the stage at a rally in Florida and taunted Harris after claiming victory.

‘Kamala, go get your f***ing ballot box’, yelled the 78-year-old before a raucous crowd of MAGA supporters in West Palm Beach.

‘I almost did my time. I came home and I want what I got to get. What’s right is right’, he finished.
