Another woman has accused Jeremy Piven of sexually assaulting her.

Anastasia Taneie has alleged that back in 2009 - when she was appearing as an extra on the HBO series 'Entourage' - Piven pushed her against a wall and started to grope her breasts and genitals.

According to Taneie, the alleged incident occurred when they were shooting on location and Piven - who starred as super-agent Ari Gold - pulled her to one side.

Piven stopped when an assistant director walked by, the extra claimed, adding that the Hollywood star subsequently asked for her to be removed from the set.

Taneie explained that she decided against making a complaint because she feared no one would believe her story.

She said: ''I was scared at the time nobody was going to believe me. I didn't want to make a scene. I just wanted to go home.''

Piven, 52, has denied all of the recent allegations made against him.

In a statement, he told BuzzFeed: ''Let me be absolutely clear, this simply did not happen.

''I would never force myself on a woman. I cannot speak as to why a person would create a story like this.''

Meanwhile, HBO said: ''We reviewed our records and did not receive any complaints against Jeremy Piven on 'Entourage'.

''HBO takes sexual harassment very seriously and we make it a priority to ensure that everyone experiences a safe and comfortable work environment.''

The latest accusation comes shortly after Piven passed a lie detector test which questioned whether he had ''fondled'' Ariane Bellamar.

The former 'Entourage' star previously denied sexual assault accusations made by the actress and two other women, Amy Meador and Tiffany Bacon Sourby.

And Piven is said to have passed all of the tests in a bid to prove his innocence.

The actor reportedly took polygraph tests regarding the three claims, and a blanket lie detector test to determine if he had ever assaulted a woman, and he passed with no signs of deception.
