Rudy Giuliani faces fresh criticism after reportedly putting his hand down his trousers during an interaction with an actress in the new Borat movie.

The former mayor of New York is reportedly shown reaching into his trousers while lying on a bed in front of the actress, who is playing the daughter of Sacha Baron Cohen’s character.

After an interview for a fake conservative TV show, Tutar, played by Maria Bakalova, took Donald Trump’s personal lawyer into the bedroom of a hotel suite for a drink, according to reviews.

Mr Giuliani, 76, was reportedly captured on hidden cameras set up by the filmmakers getting onto the the bed, where he apparently untucked his shirt and stuck his hand into his trousers.

Baron Cohen, playing the Kazakh journalist Borat, then bursts in and interrupts them while shouting “She’s 15. She’s too old for you.”

Bulgarian-born Bakalova in real life is 24 and there is no suggestion in the movie that Mr Giuliani believed she was underage.

Baron Cohen’s movie Borat Subsequent Moviefilm is out now on Amazon Prime Video.

Mr Giuliani has been at the heart of the bitter US presidential campaign with his release of emails he claims are from Hunter Biden’s laptop.

Word of the embarrassing Borat incident first became public in July when Mr Giuliani called police in New York to report it.

“This guy comes running in, wearing a crazy, what I would say was a pink transgender outfit,” Mr Giuliani told the New York Post.

“It was a pink bikini, with lace, underneath a translucent mesh top, it looked absurd.

“He had the beard, bare legs, and wasn’t what I would call distractingly attractive.

“This person comes in yelling and screaming, and I thought this must be a scam or a shakedown, so I reported it to the police. He then ran away.”

New York police reportedly investigated but found no crime had been committed.

“I only later realised it must have been Sacha Baron Cohen.

"I thought about all the people he previously fooled and I felt good about myself because he didn’t get me.”

Mr Giuliani has not responded to a request for comment.
