"Sopranos" star Vincent Pastore and mob-related rapper Tony Testa got into a wild, name-calling dust-up during a video shoot for Testa's new record.

A nephew of jailed mob boss Joseph Carmine Testa told us he had a fight with Pastore after the actor -- who played Salvatore "Big Pussy" Bonpensiero on the HBO series -- demanded a limo and top billing on the credits before he would leave the house.

According to Testa, Pastore then refused to show up for Wednesday's shoot for "Paper Chaser" at Bamonte's restaurant in Williamsburg -- leaving fellow "Sopranos" actor Joe Gannascoli, who played closet gay Vito Spatafore Sr., and Chuck Zito, who starred in HBO's "Oz," to carry on with the shoot before they, too, began bickering.

Testa, who owns three Long Island tanning salons, said, "At the last minute, Vincent didn't like the negotiated terms for the video, so I gave him some choice words. He says he's not turning up. He wants a limo to pick him up because of the rain. I called him and said, 'Take a cab, and I'll pay for it.'

"But he gets very rude and disrespectful, starts cursing on the phone, saying, 'This isn't even union. I don't know what the [bleep] this is. I need a private car to pick me up. I am not leaving my [bleep]ing house to get into a car accident to film your video.'

"I said to him, 'Listen to me, you fat mother[bleeper]: If you don't turn up to my video shoot, I'll stomp on your head.' He then sent a text to Joe saying he was just threatened by me. This isn't 'The Sopranos.' My uncle is doing life in jail. I am doing rap because it is my passion. These guys think they are celebrities. He thinks he is Kim Kardashian."

Then, during the shoot, Zito and Gannascoli started fighting about whether "The Sopranos" or "Oz" was the better show.

"Voices were raised," Testa told us.

Pastore's agent said, "This is the first I've heard of this." Zito said, "Vinnie has always been a down-to-earth guy. On a movie, they pick you up; it's normal treatment. I don't think he would expect star treatment."

Zito laughed: "The best show is 'Oz' . . . Joe took good advice and walked away. He knew he was in a losing battle."
