The 'Creed' star's pals Victoria and Isaac Oberfeld threw a star-studded bash for the actor at the restaurant La Trattoria in the principality on Wednesday (06.07.16) and Sylvester - who was accompanied by his wife Jennifer Flavin and daughters - admitted he was shocked by the party, which was attended by 88 people.

He told the newspaper Nice Matin: "I'm here at the invitation of my friend Victoria. It's a surprise for me, I didn't expect such an evening. I thought for my 70th birthday she would have offered me a hamburger and fries.

"It made me really happy to see these people, especially Prince Albert."

Albert, brought Sylvester a rare black-and-white signed photograph of his mother, Princess Grace, as a birthday present.

Despite just turning 70, Sylvester shows no signs of slowing down and is reportedly set to play a mafia boss in a new TV series.

The 'Expendables' actor is believed to be negotiating a deal for what will be his first major scripted small screen role in Antoine Fuqua's TV adaptation of Mario Puzo's novel 'Omerta'.

The book - which was published in 2000, a year after the writer's death - is the final in the author's mob trilogy, which began with 'The Godfather' and continued with 'The Last Don'.

Stallone is expected to play the mafia head at the centre of the story.

A network is not yet attached to the project, but sources told The Hollywood Reporter it will soon be shopped to cable and streaming services ahead of filming a pilot episode beginning this summer.
