BOSS BACKTRACKS ON WAL-MART

NEW YORK — The Boss is owning up to a mistake.

In an interview for tomorrow's New York Times, Bruce Springsteen says he shouldn't have made a deal with Wal-Mart for exclusive sales of a Springsteen greatest hits CD. It went on sale in Wal-Marts this month.

Some fans disapproved because Springsteen has long been a supporter of workers' rights, and Wal-Mart's labor practices have been criticized.

Springsteen told the Times he "dropped the ball on it," in not considering that issue.

Springsteen released his new CD "Working on a Dream" this week and will play at Super Bowl halftime.

COWABUNGA CALL FOR SCIENTOLOGY

NEW YORK — Bart Simpson is known for prank calls, but Nancy Cartwright, who provides Bart's voice on "The Simpsons," has been heard this week in a phone message using the voice of the cartoon kid to promote Scientology.

Cartwright, a member of the church, recorded her 60-second robocall to boost attendance at a Scientology event today.

Although she identifies herself, much of the spiel is delivered in Bart's voice, wrapping up with, "See you there, man!"

The Fox network would not comment, but "Simpsons" executive producer Al Jean said the message wasn't authorized by the show, which has never "endorsed any religion, philosophy or system of beliefs any more profound than Butterfinger bars."

BATTLE BREWING OVER BRITNEY

LOS ANGELES — A person close to Britney Spears says the singer has obtained a restraining order against former pal Osama "Sam" Lutfi and onetime boyfriend Adnan Ghalib.

Attorneys for Spears and her father, her legal conservator, got the order yesterday because Lutfi and others were trying to gain control of Spears' affairs, said the source, who requested anonymity. The exact nature of the order was not clear yesterday.

Lutfi was a manager and friend of Spears, whose mother once accused him of grinding pills into the singer's food to control her. Ghalib, a paparazzo, had dated Spears.

NOW, ABOUT THAT $3M, ZELLWEGER ...

LOS ANGELES — An attorney wants Bridget Jones' diary.

Allen Michel told a judge in Los Angeles yesterday that he wants Renee Zellweger to turn over her diary, give a deposition and provide any other documents to detail how she spent her time during a seven-week delay in the filming of 2005's "Cinderella Man" in Toronto.

Zellweger's agents negotiated a $3 million payment for the "Bridget Jones' Diary" star because of the delay, caused by Russell Crowe's dislocated shoulder.

Michel represents an insurer that says it's already paid nearly $6 million for the delay, and claims it shouldn't be liable for the money paid to Zellweger, who isn't named as a party to the lawsuit.
