New York- Hip hop mogul Irving (Irv Gotti) Lorenzo was charged yesterday with laundering more than $1 million of a notorious drug kingpin’s cash through his rap label, recording giant Murder Inc.

Lorenzo, 37, and his younger brother Christopher, known as Chris Gotti, 34, surrendered to FBI agents on an indictment that could have them singing the jailhouse blues for up to 20 years.

The brothers, who adopted the Gotti moniker in tribute to the late crime boss John Gotti, got rich producing superstars like Ja Rule and Ashanti.

But in an industry built on tough talk, prosecutors said Murder Inc. made its millions blurring the line between the studio and the street.

“When rap executives adopt pseudonyms like ‘Gotti,’ and make and promote records that glorify drugs and violence, it’s pretty clear that the thug image isn’t accidental,” said Frederick Snellings, special-agent-in-charge of the FBI’s criminal division in New York.

Brooklyn U.S. Attorney Roslynn Mauskopf said the Lorenzos conspired with notorious drug kingpin Kenneth (Supreme) McGriff, a childhood pal from Hollis, Queens, to launder McGriff’s dirty profits.

McGriff, currently doing time on a federal gun rap, was charged with racketeering and the 2001 murder of aspiring rapper Eric (E. Moneybags) Smith in Queens.

Authorities believe McGriff was behind at least six other drug-related murders including a double killing in Baltimore, sources said.

Clad in bulky parkas and construction boots, the Gotti brothers were released on $1 million bonds after pleading not guilty at their arraignment.

Outside court, Irving Lorenzo told reporters: “No way, in any way, shape or form have I done anything wrong, except make great music that the people seem to love, and that’s all that I’m guilty of.”

Chris Lorenzo’s lawyer, Gerald Shargel, who represented John Gotti, suggested the criminal charges grew out of a “cultural divide” between law enforcement and the rap industry.

But Snellings insisted the probe was “never about investigating the rap music industry. It was, and is, about investigating guns, drugs, murder and money laundering.”

Mauskopf said McGriff financed a straight-to-video flick that involved Lorenzo called “Crime Partners” with drug cash. She said Lorenzo paid another record company $500,000 in drug cash to finance the movie soundtrack.

In recent years McGriff, who founded the “Supreme Team” crack gang in the early 1980s at the Baisley Park project in Queens, had tried to pass himself off as a legit businessman.

But after his release from prison in 1995, he resumed his drug trafficking activities on a grander scale, authorities said.
