Gotti mob rat’s boast: I’m a lying woman beater

John “Junior” Gotti’s lawyers yesterday exposed mob rat John Alite as a wife-beating perjurer who lied his way through a federal court proceeding.

The prosecution’s star witness against Gotti admitted on the stand that he repeatedly lied in front of a Brooklyn federal grand jury in May 1999, when he was questioned about Gotti and Gambino mobster Ronnie “One Arm” Trucchio.

He was even hauled out of the room at one point during that hearing and warned by a prosecutor that he could be charged with perjury.

The turncoat Gambino family associate described himself yesterday in Manhattan federal court as “very good” at lying, saying, “Those days, I lied about everything.”

But Alite insisted he “wouldn’t do it here” because of a cooperation deal with the feds, who are banking on his testimony to finally convict Gotti after three hung juries since 2005.

The heavily tattooed killer also gleefully described his violence toward women — admitting he punched and slapped at least five, including his ex-wife “during the marriage, [and] before the marriage.”

Alite wickedly smiled when asked about leaving an answering-machine message in which he vowed to make a business partner’s wife perform a sex act on him while forcing the man to watch — punishment for cheating Alite out of money.

Junior’s wife, Kim, was in the gallery and waved to her husband after the testimony ended.
