ROBERT De Niro is being sued by his ex-assistant who alleges he made sexually charged comments to her, was verbally abusive and assigned her "stereotypical females duties".

The Raging Bull actor is accused by his former PA Graham Chase Robinson of swearing at her and calling her a “b***h” and a “spoilt brat”.

The then 25-year-old claims De Niro, who is best known for playing hard-nosed underworld mobsters, communicated to her in a "hostile, abusive, and intimidating manner".

In an answering machine message, the actor is heard laying into Robinson after she apparently wanted a new position.

He says: "Don't f***ing get angry with me 'cause I'm pissed off 'cause I didn't get a single thing that I need right now ... you gotta be f***ing kidding me, you spoiled brat! F**k you."

Robinson claims De Niro referred to a female business partner as a "c***."

And she alleged the actor was often drunk and would lash out at her.

She also claimed he would also joke with her about his Viagra prescription, and would ask her to "imagine him on the toilet" and allegedly suggested Robinson could get pregnant by using sperm from a male coworker.

Star's full shocking tirade According to explosive court documents, it's alleged that Robert De Niro ranted: "You f***ing don't answer my calls? How dare you. "You're about to be fired. You're f***ing history. "This is bulls**t. How dare you disrespect me. "You want another f***ing position, you want another position, then say you want another position and go off somewhere... "But don't f***ing get angry with me because I'm p***ed off because I didn't get a simple thing that I need in California, where I am for less than 24 hours. "You gotta be f***ing kidding me, you spoiled brat! F*** you! "So quit, whatever you want. "God damn you - how could you f***ing say you don't answer, you're upset. "You're living in Spain, you spoiled f***ing brat!"

De Niro actually sued her first back in August, claiming she binge-watched 55 episodes of Friends during a four-day period and used the company credit card to get fancy lunches.

Robinson has other complaints in her lawsuit, alleging De Niro would urinate during phone calls with her and ordered her to scratch his back and prod him awake when he was sleeping.

She also says De Niro stood "idly by" when one of his friends slapped her on the butt.

Robinson is suing for gender-based harassment and back wages.

De Niro is known for his outspoken language.
