CHAT show king Jay Leno gave evidence at the Michael Jackson trial yesterday — and had the jury in stitches as he plugged his TV show.

Leno, 55, turned to them as he left the witness box and joked: “I have Renee Zellweger on the show tonight.”

The jury erupted in laughter — as did lawyers and even the judge. Earlier the Tonight Show presenter told the court how he was “suspicious” of phone calls he got from the boy who accuses Jackson of molesting him.

Leno said he was often in contact with sick children and that the boy — who was suffering from cancer — began leaving voicemail messages for him in 2000.

He invited the boy to visit the NBC show’s studios. Although Jacko’s lawyers have portrayed the boy’s family as money-grabbers who targeted celebrities, Leno said he was never asked for cash.

But he was surprised by the way the boy flattered him. He said: “It did not sound like a 12-year-old. It seemed like an adult and it seemed a little scripted.”

The Jackson case has been the butt of gags on Leno’s show.

After he was subpoenaed to testify he used stand-ins to deliver his jokes about the trial.

The jury’s verdict could come next week after Jackson’s lawyers called their final witness — comic actor Chris Tucker.

The Rush Hour star first met the singer after attending a charity event for the boy.

He told the court: “I met his father. He approached me and told me that he had a kid that loved me and was dying of cancer.”

Following the event he gave the boy's trust fund $1,500 after the boy rang him to say the charity event had raised no cash.

Tucker added that he had once been called a “brother to the children” by the boy's mother.

Jacko, 46, denies child abuse. The trial in California continues.
