The news media's fevered investigation into the

Angelina Jolie

false-birth, news-media scandal has been rocked by a potentially explosive claim. Two of Jolie's confidantes tell the Associated Press - anonymously - that the celebrity news TV show

Entertainment Tonight

, which last Friday reported that Jolie and

Brad Pitt

's twins had been born, did so knowing its source was fake.

ET

insists it believed in good faith that its source for the birth report was an e-mail from Jolie's assistant

Holly Goline

.

But one of the Jolie confidantes tells the AP that the real Goline warned

ET

the info came from an impostor

hours

before show host

Mary Hart

broadcast the false report.

"

Entertainment Tonight

was told before the broadcast that their information came from an impostor," AP's source says.

ET

, which has not mentioned its report on air since Friday, continues to assert that it learned the truth days later.

Michelle Obama to host 'The View'

Michelle Obama

will join the gals as a guest host on the June 18 episode of the daytime chatfest

The View

.

Exec producer

Bill Geddie

said Obama, the wife of Democratic presidential candidate

Barack Obama

, was initially invited as a guest, but requested that she appear as a host - just as

Cindy McCain

, the wife of Republican candidate

John McCain

, did in April.

"Equal time - that's hard to argue with," Geddie said. He said the show is relatively gentle on candidates' wives. "We're tougher on the candidates than we are on the wives," he said. "We're trying to get to know them."

Guests for the June 18 episode have yet to be announced.

Fresh disaster looms for the industry

Brace yourselves, citizens: Looks like fresh product from Hollywood might dry up again.

USA Today says the nation's Bread 'n' Circuses-Industrial Complex, which is still recovering from the three-month writers' strike, may be crippled again, this time by thesps.

The 127,000-member-strong Screen Actors Guild, which has been negotiating with the Alliance of Motion Picture and Television Producers, may call for a walkout as early as June 30.

Neither side can comment because of a media blackout.

Tabloid apologizes to Ozzy

Heavy-metal survivor

Ozzy Osbourne

, 59, has accepted an undisclosed bag of $$$ and a no-doubt heartfelt apology from Brit tabloid the Daily Star for a story headlined, "Ozzy's Freak Show" that claimed the health of the beloved former reality-show patriarch gave out so badly that he collapsed twice just before he was due to host February's Brit Awards, one of Britain's most distinguished industry award shows.

Actually, all went well. Ozzy cohosted the event with his wife,

Sharon

Kelly

and

Jack

The Tatum O'Neal industry

An avalanche of follow-up stories has buried the populace in the wake of

Tatum O'Neal

's crack arrest. Everyone wants to nail the reason Tatum did it. It was the dog's fault, says the New York Post. More precisely, it was the dog's death that did it. The Post says Tatum was in despair over the demise of her beloved 16-year-old Scottish terrier,

Lena

. Does that explain it all? What about

Danny Bonaduce

, who says Tatum, the daughter of star

Ryan O'Neal

, had a lousy upbringing? Maybe it was the full moon?
