Robert de Niro has claimed his ex-assistant used his frequent flyer miles worth $300,000 and paid for dog-sitting, Pilates classes and hotels using a company credit card, according to new court documents.

The actor, 78, is suing Graham Chase Robinson for $6 million, claiming she helped herself to cash in a four-year spending spree while working for his company Canal Productions.

Robinson has launched her own legal action against de Niro which seeks $12 million in damages, alleging that the Raging Bull star was verbally abusive, made ‘sexually charged comments,’ and  subjected her to ‘unwanted physical contact.’

In newly-filed court documents obtained by RadarOnline, de Niro has included a 2019 letter from his lawyer to his ex-employee who had worked her way up from personal assistant to Vice President of Production and Finance.

I was asked to answer Bob’s recent emails. Bob is not interested in communicating with you. Please direct all correspondence concerning this matter to Bob, as the letter indicates.

Robinson was accused of using her American Express card for Uber rides, food purchases, pet sitting, grocery shopping, camera, phone, drone trips, Uber, dogsitting, flowers and dry cleaning. She also claimed she had helped herself to some petty cash. 

A former employee was accused of using more than 7 million Delta SkyMiles to travel, and then transferring an additional $4.5 million into a personal account.

Robinson was also accused of using Canal’s credit card improperly to purchase taxis and pay food expenses while in London. She was charged $2600 to stay at Montage Hotel, $654 for dinner at Nobu and $729 for a rental car.

Robinson claims she has not used her credit cards in an improper manner and raises questions about whether or not she actually made the purchase.

Robinson claimed in her lawsuit against de Niro that he only started his legal actions to premeditate Robinson’s.

“De Niro became angry at Ms. Robinson’s idea of bringing a suit challenging his conduct. According to the complaint, De Niro retaliated by striking first.  

In her own court documents, she alleged the Casino actor forced her to endure a toxic workplace where he branded her a ‘b****’ and spoke to her in a ‘hostile, abusive and intimidating manner.’ 

The actor has previously branded the lawsuit ‘completely absurd.’

But in a 2012 voicemail leaked last year De Niro can be heard shouting at Robinson, calling her a ‘spoiled brat,’ saying ‘how dare you f***ing disrespect me,’ and threatening her, saying ‘you’re f***ing history.’

According to her, such behaviour is not unusual in the legendary actor who has been accused of abusing his employees on numerous occasions. 

Alexandra Harwin, the lawyer for De Niro stated that Mr. De Niro called Ms. Robinson every day when she was intoxicated. She would often call her and berate her or curse at her. Fox Business listened to her statement in January 2020.

Harwin further claimed that Robinson had been asked to do tasks her male counterparts were never requested to, including buttoning his buttons, tying his tie, and scratching Mr. De Niro’s head.

In the lawsuit, it is also stated that she was instructed to awaken him from bed when he was asleep and place him on the toilet. 

Both cases are ongoing.
